10 Dangerous Diseases of the Heart in Islam and How to Cure Them

Introduction

According to Islam, the Heart is not only one of the organs of the body but is also the center of Faith, Sincerity, Love, Fear, Humbleness and Guidance. One’s entire life will be beautiful if one’s Heart is Pure. If, however, one Has a spirit that is ill the sweetness associated with performing outward acts of Worship will be lost.

In the present day many individuals are suffering from feelings of Anxiety, Emptiness, Jealousy, Arrogance, Pride, Anger, and a sense of Spiritual Darkness, and most do not realize that these are among the greatest Diseases of the Heart in Islam.

Allah ﷻ states in Surah Al-Baqarah:

فِي قُلُوبِهِم مَّرَضٌ فَزَادَهُمُ اللَّهُ مَرَضًا

“In their hearts there is a disease, then Allah increases for them their disease.”
(Surah Al-Baqarah 2:10)

This Ayah teaches us something frightening:

The Heart is capable of becoming Spiritually Diseased.

What is tragic is that most Individuals quickly Treat their Physical Ailments but they ignore the Spiritual Ailments of the Heart for quite some time.

What Are Diseases of the Heart in Islam?

The term Diseases of the Heart in Islam refers to spiritual illnesses that corrupt the soul and distance a person from Allah.

These diseases include:

• arrogance
• envy
• hypocrisy
• showing off
• hatred
• greed
• excessive love of dunya
• spiritual hardness

Unlike physical sickness, these diseases often remain hidden.

A person may appear religious outwardly while inwardly suffering from pride, jealousy, and insincerity.

The Prophet ﷺ said:

“Indeed, there is a piece of flesh in the body. If it is sound, the whole body is sound. If it is corrupt, the whole body is corrupt. It is the heart.”
(Sahih Bukhari)

This Hadith is one of the foundations of understanding Diseases of the Heart in Islam.

Why Spiritual Diseases Are More Dangerous Than Physical Illness

In the short term, physical sickness affects the human body (the physical form).

Spiritual illnesses, on the other hand, can utterly destroy:

• Faith
• Sincerity
• Relationships
• Worship
• The Afterlife

Imam Ibn Ata’illah (may Allah bless him) stated:

“How can the heart be bright when the mirrors of worldly lust hide it?”

So many today seem successful on the outside, but deep inside are experiencing:

Emptiness
Darkness

This is why it is very important for every Muslim to understand the) Divine Diseases of the Heart in Islam.

Iblis refused to bow to Adam عليه السلام because of pride.

إِنَّهُ لَا يُحِبُّ الْمُسْتَكْبِرِينَ

“Indeed, Allah does not love the arrogant.”
(Surah An-Nahl 16:23)

Deep Tasawwuf Reflections

1. The Heart Must Be Purified Daily

Sunni Tasawwuf teaches that the heart gathers spiritual rust every day.

Dhikr and tawbah polish it.

Imam Al-Ghazali (رحمه الله) wrote extensively about curing the Diseases of the Heart in Islam through:

• muraqabah
• self-accountability
• sincerity
• remembrance

2. The Awliya Focused on Inner Purification

Khwaja Gharib Nawaz (رحمه الله) emphasized:

“Clean the heart before decorating the body.”

True spirituality begins inwardly.

3. Dhikr Is Medicine for the Heart

Allah says:

أَلَا بِذِكْرِ اللَّهِ تَطْمَئِنُّ الْقُلُوبُ

Dhikr heals spiritual anxiety and darkness.

4. The Broken Heart Is Closest to Allah

Many Awliya Allah cried nightly in repentance.

Brokenness softens the heart.

5. Tazkiyah Is Essential

Purification of the soul is not optional.

It is central to Islam.

A wealthy man went to meet Shaykh Abdul Qadir al-Jilani (rahimahullah) asking him why he felt inside of himself so empty even though he was successful in life.

Shaykh Abdul Qadir al-Jilani (rahimahullah) answered him, “Your body is living in luxury, but your heart is living in starvation.”

Upon receiving this answer, the man cried.

Afterwards, he began to devote himself towards the remembrance of Allah (dhikr), giving charitably, and his humility allowed him to soften his heart once again.

This story beautifully explains the reality of Diseases of the Heart in Islam.
