FRIDAY SERMON: The Heart – Center of Emotions

A Scientific, Islamic, and Social Exploration

Mohammad Younis Bhat (Zahid)

The heart is the central organ of the human body, created by Allah as the command center of life. It continuously pumps blood throughout the body, supplying oxygen and nutrients to every cell. In the Qur’anic and spiritual sense, the heart (Qalb) is more than a physical organ — it is the seat of emotions, faith, purity, intention, consciousness, and moral perception. It is the place where sincerity resides and where one’s relationship with Allah develops. Islamic scholars describe the heart as a vessel that either reflects divine light and guidance or becomes stained with doubts, sins, and desires.

Importance of the Heart

Islam elevates the significance of the heart above all other organs. The Prophet Muhammad (ﷺ) said:
“Indeed, there is a piece of flesh in the body; if it is sound, the whole body is sound, and if it is corrupt, the whole body is corrupt. Indeed, it is the heart.”
This Hadith establishes that the condition of the heart determines the moral and spiritual condition of an individual.
The heart is the center of:

• Iman (faith)
• ⁠Taqwa (consciousness of God)
• ⁠Ikhlas (sincerity)
• ⁠Niyyah (intention)
• ⁠Love and fear of Allah
• ⁠Emotional stability
• ⁠Moral behavior

Thus, the heart shapes the personality, character, and destiny of a human being.

The Heart From a Scientific Perspective

Scientifically, the heart is a powerful muscular organ located in the chest, responsible for pumping approximately 5 liters of blood per minute. It beats around 100,000 times a day and maintains the circulation that sustains life. Although scientific studies traditionally focused on the brain as the control center, modern research shows that the heart contains more than 40,000 sensory neurons, creating what researchers call a “heart-brain connection.”
This means that the heart can sense, respond, and send signals to the brain, influencing emotions, thoughts, memory, and stress.
In simple terms:
science supports what Islam stated 1400 years ago — that the heart influences human behavior and emotions.

The Heart in the Qur’an and Islam

The Qur’an mentions the heart over 100 times, referring to it as the place of guidance or misguidance.
A pure heart brings peace, clarity and faith. A corrupted heart brings confusion, arrogance, anger and misguidance.
Allah says:

“Verily, it is not the eyes that are blind, but the hearts within the chest.” (Qur’an 22:46)

“On that Day, neither wealth nor children will benefit anyone, except the one who comes to Allah with a sound heart.” (Qur’an 26:88–89)

From these verses, it is clear that the heart determines a person’s final success in the Hereafter.

Thirteen (13) Types of Hearts in the Qur’an and Sunnah

1. The Sound Heart (Qalb Saleem)

Pure, sincere, free from shirk, hypocrisy, and hatred.
This is the heart that Allah accepts.

2. The Believing Heart (Qalb Mu’min)

Firm in faith, filled with trust in Allah. Believers find peace and motivation in such a heart.

3. The Tranquil Heart (Qalb Mutma’inn)

A heart content with Allah’s decree.
“Verily, in the remembrance of Allah do hearts find rest.” (13:28)

4. The Soft and Humble Heart (Qalb Khashi’)

A heart that trembles at the mention of Allah and is moved by the Qur’an.

5. The Repentant Heart (Qalb Munib)

Frequently returns to Allah, seeking forgiveness and purity.

6. The Dead Heart (Qalb Mayyit)

A heart devoid of faith, compassion, or spiritual awareness. This heart follows desires blindly.

7. The Sick Heart (Qalb Mareed)

Weak faith, mixed intentions, jealousy, arrogance.
Mentioned in Qur’an (2:10).

8. The Hard Heart (Qalb Qasi)

Insensitive, cruel, and spiritually numb.
Allah says: “Then your hearts became hardened…” (2:74)

9. The Sealed Heart (Qalb Makhtoom)

A heart on which Allah has set a seal because of persistent disobedience. (2:7)

10. The Deviated Heart (Qalb Zaa’igh)

A heart that inclines toward misguidance and doubts.

11. The Fearful Heart (Qalb Wajil)

Full of awe of Allah, and immediately feels remorse after sin. (23:60)

12. The Understanding Heart (Qalb Yafqahu)

A heart that uses reason, reflection, and spiritual insight.

13. The Blind Heart (Qalb A’ma)

Unable to perceive truth.
“Indeed it is hearts that go blind, not the eyes.” (22:46)

Emotional Values and the Heart

Humans experience love, grief, anger, compassion, kindness and sadness through the heart.
Islam encourages a heart that is:

• Gentle
• ⁠Forgiving
• ⁠Generous
• ⁠Loving
• ⁠Humble
• ⁠Courageous
• ⁠Stable

The Prophet (ﷺ) emphasized emotional balance through the heart, reminding believers to control hatred, jealousy and pride.

Difference Between the Heart and the Mind

Heart (Qalb)

• Seat of emotions
• ⁠Root of intention & sincerity
• ⁠Gateway to spiritual wisdom
• ⁠Controls moral direction
• ⁠Determines faith

Mind (‘Aql)

• Seat of logic
• ⁠Processes information
• ⁠Makes rational decisions
• ⁠Thinks critically

Islam teaches harmony between heart and mind.
A heart without intellect becomes misguided.
A mind without a purified heart becomes arrogant.

Misuse of the Heart in Modern Generations

Today’s young generation often misuses the concept of the heart by:

• Calling every emotional impulse “love”
• ⁠Following desires instead of guidance
• ⁠Confusing temporary attraction with long-term commitment
• ⁠Allowing social media to control emotions
• ⁠Overvaluing feelings over moral principles
• ⁠Using the “heart” as an excuse for irresponsible choices

The result is emotional instability, broken relationships, loss of identity, and spiritual emptiness.

Islam teaches that the heart must be disciplined, purified, and guided — not worshipped.

Conclusion

The heart is the most powerful organ of human existence — physically, emotionally, and spiritually.
Science confirms its influence; the Qur’an emphasizes its role; the Sunnah highlights its condition.
A pure heart leads to a pure life, a peaceful soul, and eternal success.
A corrupt heart leads to confusion, arrogance, sin, and ultimate loss.

Therefore, the responsibility of every believer is to purify the heart, enlighten it with Qur’an, soften it with remembrance, and protect it from desires and arrogance.

Only a sound heart will benefit us in this world — and in the Hereafter.
