This research paper, titled "Dhikr as an Islamic act of mindfulness," explores the traditional Islamic practice of dhikr (remembrance of God) through psychological, neurophysiological, and cross-cultural lenses. Authored by Nataliya Barinova under the supervision of Dr. Filius Iakhin, the study investigates how mindful repetition of sacred Islamic formulas serves as a spiritually grounded form of mindfulness and self-therapy. The paper begins by establishing the linguistic, Quranic, and Hadith foundations of dhikr, distinguishing between silent (kafi) and vocalized (jali) forms. It traces the historical development of dhikr within Sufism (tasawwuf) and its cross-cultural adaptation across different regions, incorporating Al-Ghazali's four-stage progression of heart-centered invocation. Furthermore, the work analyzes the psychophysiological mechanisms of dhikr, explaining how rhythmic recitation and controlled breathing activate the parasympathetic nervous system, lower cortisol levels, stimulate melatonin release, and alter frontal lobe activity to promote positive emotional states. Finally, the study aligns dhikr with modern mindfulness research, framing it through the classical Islamic concept of muraqabah (attentive self-awareness under Divine watch). The author concludes that mindful dhikr enhances intellectual, emotional, and spiritual quotients, serving as an accessible, cost-free psychological intervention for reducing anxiety, depression, and stress while fostering holistic well-being.
Introduction:
The Introduction highlights the growing intersection between religious practices and psychological science, noting how spiritual traditions offer effective therapeutic tools. It introduces dhikr alongside other global verbal psychotechnics like Hindu/Buddhist mantras and Eastern Christian hesychasm. The primary objective is established: analyzing mindful or quiet dhikr (dhikr hafi) as a structured mindfulness practice that fosters psychological well-being, peace, and present-moment awareness for Muslims.
Chapter 1. Dhikr: concept and content:
This chapter defines dhikr from its Arabic root meaning "remembering" or "mentioning." It details core ritual phrases—such as tasbih, tahmid, takbir, istighfar, and tahlil—and categorizes dhikr into silent (kafi) and loud (jali) types. Examining Islamic scriptural texts, it notes that dhikr appears 292 times in the Quran, functioning both as a human obligation to remember God and as a Divine reminder conveyed through prophets and scripture.
Chapter 2. Cross-cultural aspects of dhikr:
This chapter explores the historical evolution of dhikr within Sufism (tasawwuf) from the 8th–10th centuries onward and its spread through Sufi orders (tarikat). It presents Al-Ghazali's model of four developmental stages of dhikr—moving from mechanical tongue recitation to complete absorption in the Divine. It also addresses how dhikr adapted to local ethno-regional traditions, sometimes evolving into folk practices resembling local customs or shamanic trance rituals.
Chapter 3. Psychophysiology of dhikr:
This chapter focuses on the neurobiological and somatic mechanisms of dhikr. It explains how repetitive recitation combined with breath control stimulates the vagus nerve and parasympathetic system, suppresses sympathetic activity, decreases cortisol, and promotes melatonin production. Neurologically, dhikr activates the brain's left frontal lobe to generate positive affect, while psychologically it functions as a therapeutic cleanser against negative emotions like arrogance, envy, and anxiety.
Chapter 4. Dhikr as an act of mindfulness:
This chapter compares secular mindfulness models with Islamic spirituality. It critique secular approaches for lacking ethical grounding and introduces muraqabah as the authentic Islamic model of Divine-mindfulness. The author explains how dhikr creates a safe internal and metaphorical space, drawing parallels between dhikr circles and "gardens of Paradise." Mindful dhikr is shown to cultivate emotional intelligence, empathy, cognitive clarity, and a deep sense of life purpose.
Conclusion:
The Conclusion synthesizes the paper's findings, affirming that dhikr is a universal Islamic practice not limited to Sufi orders. It highlights the multifaceted benefits of mindful dhikr across intellectual, emotional, and spiritual dimensions. The section emphasizes that dhikr provides a universally accessible, free, and safe self-therapy tool that helps individuals overcome modern psychological stressors and achieve lasting inner peace.

The research paper titled "Dhikr as an Islamic act of mindfulness," authored by Nataliya Barinova (PG21020054) under the supervision of Dr. Filius Iakhin (ITKI 6300, 2024), presents a comprehensive academic investigation into the Islamic practice of dhikr (remembrance of God) and its therapeutic alignment with modern psychological mindfulness. The paper spans twenty-eight pages and is organized into an Introduction, four distinct main chapters, a Conclusion, and a Bibliography containing primary and secondary sources.
In the Introduction, the paper situates itself within the contemporary clinical trend of incorporating religious and spiritual traditions into psychological research and psychotherapeutic interventions. Over recent decades, empirical inquiries have demonstrated strong positive correlations between religious practices and psychological well-being, including higher life satisfaction, happiness, and positive affect. The author notes that spiritual verbal formulas—termed "psychotechnics"—are present across world religions, including mantras in Hinduism and Buddhism, hesychasm (mental prayer) in Eastern Christianity, and dhikr in Islam. These practices share typological parallels in how they induce specific mental and emotional states through structured repetition. The explicit aim of the paper is to examine mindful dhikr, particularly silent or quiet dhikr (dhikr hafi) performed in solitude, as an Islamic act of mindfulness that produces measurable psychological benefits.
Chapter 1 establishes the conceptual and textual definitions of dhikr. Linguistically derived from the Arabic root meaning "remembering," "mentioning," or "memory," dhikr refers to the act of recalling Allah through various spiritual activities, including reciting Quranic verses, praising Divine attributes, and engaging in reflective contemplation. In its specific ritual form, dhikr involves repeating short Arabic phrase-formulas. The core formulas analyzed include tasbih ("Subhan Allah"), tahmid ("Alhamdu lillah"), takbir ("Allahu akbar"), istighfar ("Astaghfirullah"), and tahlil ("La ilaha illallah"). The author categorizes dhikr into two primary forms: loud or spoken dhikr (dhikr jali), often practiced collectively with rhythmic movements, and silent heart-centered dhikr (dhikr kafi), practiced individually in solitude. Textual analysis shows that the root of dhikr appears 292 times across 264 Quranic verses. The paper divides these occurrences into two main contextual groups: human obligation to remember God (dhikr Allah, as seen in verses 18:24, 33:41, and 13:28) and Divine reminders sent to humanity in the form of scriptures, past prophets, and Prophet Muhammad. Hadith literature, such as Sahih al-Bukhari 4832, further reinforces dhikr as a dynamic, reciprocal interaction between God and the believer.
Chapter 2 addresses the cross-cultural and historical trajectory of dhikr, focusing on its development within Sufism (tasawwuf). Arising between the 8th and 10th centuries and consolidating through Sufi brotherhoods (tarikat) by the 11th century, Sufism established dhikr as its foundational pillar. The author outlines the classic four-stage developmental model of dhikr formulated by the scholar Al-Ghazali in his work "The Revival of Religious Sciences": (1) dhikr of the tongue, where recitation occurs mechanically with minimal heart involvement; (2) voluntary recitation with effort, where the heart is periodically engaged through conscious willpower; (3) effortless heart recitation, where the heart is entirely absorbed in dhikr and effort is required to disconnect; and (4) complete absorption in the Almighty, where the repetition formula disappears and total spiritual union/annihilation of self-experience occurs. The chapter also explores how dhikr adapted as Islam spread globally, intersecting with local ethno-regional traditions and occasionally evolving into folk practices with shamanic or trance-like characteristics.
Chapter 3 provides a detailed analysis of the psychophysiology of dhikr. The practice is described as a verbal psychotechnique operating on neurophysiological interactions between consciousness, subconsciousness, and speech. In Islamic scripture, emotional and mental states are projected onto the physical chest and heart. The author demonstrates that rhythmic dhikr recitation accompanied by breath control lowers the respiratory rate by nearly half, increases vagal nerve stimulation, activates parasympathetic nervous system dominance, and suppresses sympathetic arousal. This biological shift leads to muscle relaxation, reduced cortisol levels, and stimulation of the hypothalamus and pineal gland, promoting melatonin release and sleep quality. Brain imaging studies cited in the chapter indicate that dhikr repetition correlates with increased left frontal lobe activity, which is directly responsible for generating positive affect and reducing emotional tension. Psychologically, dhikr functions as "soul training," offering emotional regulation, lowering stress, and alleviating psychological maladies such as envy, arrogance, and anger.
Chapter 4 examines dhikr through the lens of modern mindfulness. Secular mindfulness is defined as non-judgmental, present-moment awareness. While secular models detach meditation from religious origins, the paper argues that Islamic spirituality inherently incorporates Divine-mindfulness through the construct of muraqabah (vigilant self-awareness and contemplation of God's constant presence). Unlike secular approaches, muraqabah provides an ethical framework rooted in Divine connection. Merely striving to maintain muraqabah is itself classified as dhikr. The chapter details how practicing dhikr creates a perception of safe, sacred space within the believer's mind and body, frequently conceptualized in Islamic culture as a "garden of Paradise" (referencing Al-Tirmidhi 3510). Mindful dhikr enhances emotional intelligence, builds empathy, strengthens cognitive control, and provides deep existential purpose.
In the Conclusion, the author synthesizes these multidisciplinary insights, emphasizing that dhikr is a universal Islamic practice available to all believers beyond specific Sufi affiliations. Mindful dhikr exerts a transformative effect on the intellectual, emotional, and spiritual quotients (IQ, EQ, SQ) of the practitioner. It acts as a free, accessible, and safe self-therapeutic tool that mitigates modern stress, fosters emotional resilience, and establishes lasting peace of heart and mind.

Introduction:
The Introduction opens by observing a major contemporary paradigm shift in psychological research: the active integration of cultural and religious teachings into psychotherapeutic frameworks. Over recent decades, scholars have extensively investigated the link between spiritual convictions and mental health, demonstrating that religious practices correlate positively with psychological well-being metrics such as life satisfaction, positive affect, and overall happiness. The text identifies that various world religious and mystical traditions utilize spiritual verbal practices—termed psychotechnics—to induce beneficial psycho-emotional states. Examples include mantras in Hinduism and Buddhism, hesychastic mental prayer in Eastern Orthodoxy, and dhikr in Islam. Researchers have demonstrated typological parallels among these techniques regarding their execution and mental outcomes. Within this context, the paper defines its primary objective: to analyze dhikr as a structured mindfulness practice for Muslims and evaluate its positive psychological consequences. The author specifies that the study focuses primarily on mindful or quiet dhikr (dhikr hafi), performed in solitude, which cultivates present-moment awareness, inner tranquility, emotional stability, and existential clarity.
Chapter 1. Dhikr: concept and content:
Chapter 1 provides a comprehensive examination of the linguistic, ritual, and textual dimensions of dhikr. Linguistically derived from the Arabic word meaning "remembering," "mentioning," or "memory," dhikr refers to the intentional act of recalling Allah through sacred speech, prayer, Quranic recitation, and meditation. In daily Islamic practice, dhikr consists of repeating specific phrase-formulas in Arabic a set number of times, serving as an obligatory or recommended addition to daily worship. Key formulas detailed in the chapter include: tasbih ("Subhan Allah" - Glorified/Pure is Allah), tahmid ("Alhamdu lillah" - Praise be to Allah), takbir ("Allahu akbar" - Allah is great), istighfar ("Astaghfirullah" - I ask God's forgiveness), and tahlil ("La ilaha illallah" - There is no God but Allah). The text classifies dhikr into two broad operational modes: silent heart-based dhikr (dhikr kafi), practiced individually in quiet reflection, and vocal/loud dhikr (dhikr jali), often performed collectively with physical movement.
The chapter conducts an extensive scriptural analysis, noting that the root of dhikr appears 292 times in 264 Quranic verses. These references are organized into two primary contextual categories. First, dhikr signifies the direct obligation of the believer to maintain constant divine remembrance (dhikr Allah) to focus the human psyche on God (citing verses 20:14, 18:28, 13:28, 33:41, and 2:152). Second, dhikr refers to Divine reminders sent to humanity, encompassing holy scriptures, ancient prophets, and Prophet Muhammad himself (citing verses 21:50, 36:69, 12:104, and 16:43). Furthermore, the chapter cites foundational Hadith literature, notably Sahih al-Bukhari 4832, where God describes a intimate reciprocal relationship with the rememberer: "I am with him whenever he remembers Me... if he mentions Me in his soul, I call him in myself." The author concludes that dhikr functions as a two-way communication channel between God and humanity, comforting the heart and producing psychological equilibrium.
Chapter 2. Cross-cultural aspects of dhikr:
Chapter 2 details the historical evolution and cross-cultural diffusion of dhikr across the Muslim world. While rooted directly in the Quran and Sunnah, dhikr acquired a refined systematic role through the emergence of Sufism (tasawwuf). Historically developing between the 8th and 10th centuries across Iraq, Iran, Syria, India, Central Asia, and Transcaucasia, Sufism transitioned from individual asceticism into an organized religious-philosophical methodology. By the 11th century, Sufi orders (tarikat) expanded, turning dhikr into their core spiritual exercise and becoming prominent spiritual powers across Central Asia and beyond.
The chapter highlights the theoretical work of the classical scholar Al-Ghazali from his masterwork "The Revival of Religious Sciences." Al-Ghazali emphasized that verbal recitation without heart involvement lacks spiritual benefit, establishing a four-stage progression for dhikr: (1) Dhikr of the tongue, where recitation is purely verbal with minimal heart engagement; (2) Voluntary recitation with effort, where conscious willpower periodically draws the heart into remembrance; (3) Effortless heart engagement, where the heart becomes continuously engulfed in dhikr and effort is required to disengage from it; and (4) Complete divine absorption, where the formula itself dissolves and the practitioner achieves complete spiritual focus on Almighty God, leading to the annihilation of self-centered ego experience. Additionally, the chapter analyzes how dhikr interacted with local ethno-regional cultures during Islam's expansion. In some regions, orthodox Sufi dhikr adapted into folk traditions containing pre-Islamic, magical, or shamanic trance elements, underscoring the necessity of evaluating dhikr within its specific cultural and historical settings.
Chapter 3. Psychophysiology of dhikr:
Chapter 3 examines the biological, neurological, and physical dimensions of dhikr. The author defines dhikr as a verbal psychotechnique that leverages interactions between speech, consciousness, subconsciousness, and neurophysiology. In Islamic scriptural psychology, mental and emotional reactions are conceptualized as physical realities residing within the chest and heart area (citing Quran 13:28, 18:28, and 39:23). Islamic tradition frequently utilizes metaphors comparing prayer and Quranic recitation to "food for the soul" and physical medicine for bodily and emotional ailments (citing Quran 17:82 and Sahih al-Bukhari 5051).
From a modern scientific perspective, the chapter details how rhythmic dhikr recitation accompanied by breath control alters bodily physiology. During quiet dhikr practice, breathing becomes slow and uniform, dropping to roughly half its normal rate. This physiological slowing stimulates the vagus nerve, enhances parasympathetic nervous system tone, and suppresses sympathetic activity, resulting in decreased muscle tension and lower systemic blood pressure. This calming cascade signals the hypothalamus, which prompts the pineal gland to synthesize and release melatonin, facilitating stress reduction and improved sleep architecture. Neurologically, repetitive dhikr activates the left frontal lobe of the brain, a region critical for generating positive emotional states and reducing cognitive anxiety. Cortisol levels decrease significantly following dhikr therapy. Psychologically, dhikr operates as an intensive form of "soul training," freeing the mind from rationalistic logic overload, connecting the individual with intuitive awareness, and resolving internal personality splitting. Consequently, regular dhikr clears negative emotional impurities such as envy, arrogance, hatred, and chronic anxiety.
Chapter 4. Dhikr as an act of mindfulness:
Chapter 4 presents a comparative analysis between secular psychological mindfulness and Islamic spiritual practice. Secular mindfulness is defined as non-judgmental, present-moment awareness of internal sensations, thoughts, and feelings, promoting self-regulation and emotional stability (citing Parrott, 2017). However, the author offers a critical perspective on secularized mindfulness models, noting that they detach meditation from its original faith-based roots and ethical frameworks, which leaves the technique vulnerable to misuse. In contrast, Islam provides an ethically grounded model termed Divine-mindfulness, embodied in the classical concept of muraqabah.
Derived from the Arabic root meaning "to watch or observe attentively," muraqabah denotes an active state of vigilant self-awareness rooted in the conscious realization that Allah is continuously watching over the individual. Struggling to maintain muraqabah is explicitly categorized as a supreme form of dhikr. The chapter explains that dhikr creates a distinct psychological perception of safe, sacred space. Based on linguistic metaphors, practitioners perceive dhikr as a protective environment that insulates them from earthly stressors and spiritual harms. The author highlights a Hadith from Al-Tirmidhi (3510) in which Prophet Muhammad describes circles of dhikr as "gardens of Paradise." Furthermore, mindful dhikr activates all three major human dimensions: intellectual quotient (IQ) by enhancing focus and critical self-reflection; emotional quotient (EQ) by cultivating empathy, patience, and emotional control; and spiritual quotient (SQ) by connecting the individual directly to Divine presence and existential purpose.
Conclusion:
The Conclusion synthesizes the core findings of the entire research paper. It affirms that dhikr is a foundational pillar of Islamic life, serving as the primary vehicle for deepening faith and establishing closeness to Allah. The author emphasizes that while modern scholarship frequently associates dhikr exclusively with Sufi orders, it is fundamentally a universal Islamic practice common to all Muslims through various acts of worship, including Quranic reading, daily prayers, and verbal praises.
The section summarizes the multidimensional benefits of mindful dhikr. Intellectually, regular practice enhances cognitive functions, memory, concentration, and conceptual understanding. Emotionally, it boosts emotional intelligence, empathy, and self-awareness while relieving depression, anxiety, anger, and despondency. Spiritually, it aligns human consciousness with a higher power, imbuing life with profound meaning and direction. The author concludes that for modern individuals navigating stressful environments, mindful dhikr represents a free, safe, universally accessible, and highly effective therapeutic intervention that can be practiced anywhere and at any time to achieve psychological harmony and spiritual peace.
