In Islam, the word “qalb” holds deep spiritual significance. While it is commonly translated as “heart,” its meaning goes far beyond the physical organ. The Arabic word “qalb” originates from the root word qa-la-ba, meaning “to turn” or “to transform.”
This subtle meaning tells us a lot: the qalb is something that turns, changes, and is in constant motion. This aligns with the way human emotions, thoughts, and states of faith are never fixed; they are constantly evolving.
When discussing the meaning of qalb in Islam, we refer to the center of a person’s inner being, or their consciousness. It’s the part of us that processes spiritual truth, holds intentions, and interacts with divine guidance.
Many scholars emphasize that the qalb in Islam is not the same as the brain or the mind, although it focuses on both aspects. It’s a spiritual center, capable of understanding, rejecting, believing, or denying.
It can be healthy or sick, pure or corrupted. This dynamic and transformative nature makes the study of the meaning of qalb especially important for anyone trying to live a life that is based around spirituality.
The qalb is mentioned over 130 times in the Quran, which alone shows how important it is to Islamic thought. Each mention offers a different perspective; sometimes it’s about understanding and a way towards belief, and other times it’s described as darkened or sealed due to sin.
One of the most cited verses related to the meaning of qalb is from Surah Ash-Shu’ara (26:88-89):
“The Day when neither wealth nor children will be of any benefit, except for he who comes to Allah with a sound heart (qalb salim).”
This verse underlines that in the Hereafter, what truly matters is the state of the heart. A qalb salim is one that is pure, free from disease, and full of sincerity and faith.
Another important verse is from Surah Qaf (50:37):
“Indeed in that is a reminder for whoever has a heart (qalb) or who listens while he is present (in mind).”
This suggests that the qalb is not just a passive organ but an active participant in reflection and guidance. It is not just about pumping blood and keeping you alive, but has to do with everything we do in our lives.
The Prophet Muhammad (peace be upon him) also emphasized the heart’s role in faith and behavior. One of the most famous hadiths on the subject says:
“There is a piece of flesh in the body; if it is sound, the whole body is sound; and if it is corrupted, the whole body is corrupted. Verily, it is the heart (qalb).”
This hadith helps us understand that the state of the heart is reflected in our actions, choices, and even our character. The meaning of qalb here becomes synonymous with the moral and spiritual compass of a human being. It further becomes the center of our Niyyah, or intentions behind what we do.
Scholars of Islam and Sufi teachers have described various states of the qalb, which reflect the spiritual condition of a person. These states aren’t just theoretical; they’re very practical, and most of us experience shifts between them over our lives.
This is the ideal state of the heart, the one we all aspire to. A qalb salim is free from spiritual diseases like envy, arrogance, hypocrisy, and hatred. It’s filled with love for Allah, sincerity, humility, and trust. It’s a heart that reflects the light of guidance and is deeply connected to truth.
This heart is not dead, but it’s struggling. A qalb marīḍ is filled with conflicting feelings; maybe it believes, but doubts still creep in. Perhaps it wants to be good, but is pulled by worldly desires.
This is the heart that many of us struggle with. It’s not a bad thing in itself, but it needs attention or treatment. The qalb, or heart, in this state reveals its vulnerability and need for purification.
A qalb mayyit is a heart that is spiritually lifeless. It’s indifferent to right and wrong, it’s numb to divine reminders, and it’s often completely consumed by dunya (worldly life). This state is deeply dangerous because it removes a person from the mercy and light of Allah.
This is a beautiful state where the heart is always returning to Allah. It might make mistakes, but it doesn’t stay in error. A qalb munib is soft, reflective, and humble. It knows that perfection isn’t possible, but sincerity is.
In the Islamic worldview, the qalb is not just about emotions; it’s the seat of intellect, will, and spiritual insight. In fact, many scholars argue that true understanding comes not from the brain, but from a sound heart.
In Surah Al-Hajj (22:46), Allah says:
“Have they not traveled through the land so that they may have hearts (qalb) with which to understand and ears with which to hear?”
Here, the qalb is clearly being used as the organ of comprehension. This means that faith and knowledge in Islam are not just intellectual; they are deeply emotional and spiritual. Understanding the meaning of qalb is crucial to grasping how we perceive and respond to divine guidance.
Sufis speak often of the qalb as the mirror of the soul. According to them, when the qalb is clean, it reflects the light of Allah. But when it’s dirty with sins, it becomes cloudy and unable to perceive the truth.
That’s why regular purification of the heart is emphasized. They often talk about layers of the heart, from the outer layer to the deeper qalb, ruh (spirit), and so on. All of them start with a healthy qalb.
It’s interesting to note that the Quran also uses terms like fu’ad and sadr to talk about the heart or chest. Qalb is the core that turns, fu’ad refers to intense emotional experience, and sadr is more like the outer chest, which can be tight or open depending on one’s inner state. Understanding these layers adds to the meaning of qalb in Islamic spirituality.
Once we understand the meaning of qalb and its importance, the next question is: how do we keep it healthy?
Purifying the heart isn’t something you do once and forget about; it’s an everyday thing. Our hearts pick up a lot of dirt from the world around us: jealousy, pride, anger, laziness, and sometimes just plain distractions.
The goal is to keep cleaning it, just like you’d clean your room if it got messy. One of the best ways to do that is by remembering Allah. Simple acts, such as saying SubhanAllah, Alhamdulillah, and La ilaha illa Allah, can soften a hard heart and bring peace within.
Reading the Quran, making sincere du’a, and asking for forgiveness regularly are also beneficial. It’s also about watching what you feed your heart, what you watch, listen to, and think about really matters.
Being around good people makes a big difference. If you’re around those who remind you of Allah, it becomes easier to stay focused and positive.
And don’t worry if you make a mistake sometimes. Everyone slips. What matters is that you keep turning back to Allah. The more you turn to Him, the cleaner your heart becomes. A pure heart makes everything in life feel lighter; it helps you connect better with others, with yourself, and most importantly, with your Creator.
