Sincerity (Ikhlas) in Islam

Two people can perform the very same deed — stand in the same row for prayer, give the same amount in charity, make the same long journey — and yet the two deeds can weigh completely differently with Allah. The difference is not in anything the eye can see. It lies in the intention hidden inside the heart.

That hidden quality is called ikhlas: sincerity. It means doing a deed for Allah alone, wanting Him and His reward, and not mixing the act with a desire to be seen, praised, or repaid by people. Ikhlas is not an advanced topic for scholars only. As the texts below show, it is the very foundation on which every deed stands, because Allah judges a deed first by the purpose for which it was done.

In this article we look at what the Quran says about worship made exclusively for Allah, and at the most famous hadith ever spoken about intentions — the hadith with which Imam al-Bukhari opened his great collection.

1. Ikhlas in the Quran: Submission Made Exclusively for Allah

Allah describes the command given to the people before us — and to us — in Surah al-Bayyinah:

وَمَآ أُمِرُوٓا۟ إِلَّا لِيَعْبُدُوا۟ ٱللَّهَ مُخْلِصِينَ لَهُ ٱلدِّينَ حُنَفَآءَ وَيُقِيمُوا۟ ٱلصَّلَوٰةَ وَيُؤْتُوا۟ ٱلزَّكَوٰةَ ۚ وَذَٰلِكَ دِينُ ٱلْقَيِّمَةِ

“they were not ordered but to worship Allah, making their submission exclusive for him with no deviation, and to establish Salāh and pay Zakāh. That is the way of the straight religion.” (Quran 98:5)

Read the verse slowly and notice what it actually commands. The order was not simply “worship.” It was to worship Allah while “making their submission exclusive for him with no deviation” (Quran 98:5). That one phrase is the Quran’s own definition of ikhlas: the submission — the devotion, the obedience, the worship — is made exclusive for Allah. No share of it is directed to anyone else, and the heart does not deviate toward being noticed, thanked, or admired.

Then the verse names two concrete, outward deeds: establishing the Salah and paying the Zakah. This matters. Sincerity is not a feeling that replaces action; it is the spirit inside real, performed worship. A person who wants to learn how to pray Salah properly is learning one of the very deeds this verse names — and the verse teaches him to guard the inside of that deed just as carefully as its movements. The verse then closes by calling this exclusive, sincere worship “the way of the straight religion” (Quran 98:5) — sincerity is not an optional decoration on the religion; it is described as the straight religion itself.

Notice, too, how the verse speaks of the command: “they were not ordered but to worship Allah” (Quran 98:5). Sincerity is not presented as a later refinement added for the especially pious. From the very beginning, this exclusiveness was the order itself. Think about what the word “exclusive” shuts out. A deed done for Allah and for a reputation is no longer exclusive. A prayer offered to Allah and to the opinion of the person standing next to us has already deviated. Ikhlas, then, is a kind of purity of direction: one deed, one direction — toward Allah alone.

2. The Hadith of Intentions: Every Person Gets What He Intended

The most famous statement of the Prophet ﷺ on this subject was narrated by Umar ibn al-Khattab, who heard the Messenger of Allah ﷺ say:

“The reward of deeds depends upon the intentions and every person will get the reward according to what he has intended. So whoever emigrated for worldly benefits or for a woman to marry, his emigration was for what he emigrated for.” (Sahih al-Bukhari 1 — Sahih)

This is the very first hadith recorded in Sahih al-Bukhari, and its opening position is itself a lesson: before a single ruling about prayer, fasting, or charity, the believer is taught the scale by which all of them will be weighed — “The reward of deeds depends upon the intentions” (Sahih al-Bukhari 1 — Sahih). The deed is the body; the intention is its soul. A body without a soul is lifeless, and a deed without a sincere intention does not reach what its doer hoped for.

Notice the exact promise that follows: “every person will get the reward according to what he has intended” (Sahih al-Bukhari 1 — Sahih). Allah’s dealing with us is perfectly precise. Nothing sincere is lost, and nothing done for show is quietly upgraded into sincerity after the fact. What you aimed at is what you receive.

3. One Journey, Two Destinations: The Example of Emigration

To make this principle unforgettable, the Prophet ﷺ illustrated it with the greatest outward sacrifice of his time: the hijrah, emigration for the sake of Allah. In Sahih Muslim, Umar ibn al-Khattab narrates the same teaching with wording that spells out both sides:

“(The value of) an action depends on the intention behind it. A man will be rewarded only for what he intended.” (Sahih Muslim 1907a — Sahih)

“The emigration of one who emigrates for the sake of Allah and His Messenger (ﷺ) is for the sake of Allah and His Messenger (ﷺ)” (Sahih Muslim 1907a — Sahih)

“and the emigration of one who emigrates for gaining a worldly advantage or for marrying a woman is for what he has emigrated.” (Sahih Muslim 1907a — Sahih)

Picture the scene the hadith describes. Two men leave their homes on the same day, travel the same road, endure the same heat and fear, and arrive in the same city. Outwardly, their emigrations are identical — anyone watching would call both of them emigrants for Allah. Yet one of them travelled for Allah and His Messenger, and his emigration is accepted as exactly that. The other travelled chasing a business gain or a marriage, and his emigration counts as exactly that — nothing more. The road was the same; the destination in Allah’s sight was set by the heart before the journey even began.

This is why this hadith works as a scale for every deed, not only for emigration. Whatever we “travel toward” in our actions — a prayer, a donation, a degree, a post shared online — we will arrive at the thing we actually intended.

The example also carries a protection inside the warning. People judge the journey: they see the miles, the effort, the sacrifice. But people cannot see the aim, and they often get it wrong in both directions — praising a deed that was done for them, and overlooking a deed that was done purely for Allah. The emigrant who travelled sincerely, yet was misunderstood by everyone around him, loses nothing: his emigration “is for the sake of Allah and His Messenger (ﷺ)” (Sahih Muslim 1907a — Sahih), and that verdict is recorded by the One who knows the intention exactly. Ikhlas makes a believer independent of audiences. He no longer needs the deed to be witnessed in order for it to be worth doing.

4. Why Identical Deeds Can Carry Different Rewards

These two texts explain something every believer has observed. One person gives charity and it lifts him; another gives the same amount and it leaves his heart emptier, because he gave it for a reputation. One student learns sacred knowledge and it humbles him; another learns the same pages to win arguments. One man remembers Allah quietly in the corner of the mosque — the kind of deed described in the virtues of dhikr — and it is heavy with Allah precisely because no one else saw it.

The hadith of Muslim gathers the reason into one line: “(The value of) an action depends on the intention behind it” (Sahih Muslim 1907a — Sahih). The value of a deed with Allah is not fixed by its size, its cost, or its audience. Its value rises and falls with the intention behind it.

At the same time, intention never replaces the deed itself. The verse of Surah al-Bayyinah commands actual worship — Salah established and Zakah paid — performed with exclusive submission. Ikhlas is the soul of the deed, and a soul still needs a body. The believer therefore works on both: he performs the deed correctly, and he purifies the reason for which he performs it.

Apply the same scale across an ordinary week and it explains a great deal. A fast kept quietly, known only to Allah, and a fast announced to everyone who will listen begin from the same sunrise and end at the same sunset — yet the hadith tells us their value is set by what was intended in between. Serving one’s parents can be a burden performed for appearances, or an act of worship performed for Allah; the hands do the same work either way. Even earning a living changes character with intention: providing honestly for one’s family, intending obedience and trust in Allah, is a different deed inwardly from the same hours worked for pride and display. The actions on the surface are counted by people. The intentions underneath them are what Allah counts.

5. Guarding the Intention in Ordinary Days

How does a person protect something as invisible as an intention? The texts themselves suggest the way: since reward follows what we intend, the practical work of ikhlas is the work of honestly watching what we intend. The following are simple reflections drawn from that principle.

Renew the intention before the deed. A short pause before prayer, charity, or study — silently naming for Whom it is done — turns a habit back into worship. The deed may take a minute; the pause takes a second, yet it is the second that gives the deed its direction.

Guard the intention during the deed as well. Intentions rarely collapse all at once; they drift. A prayer that began for Allah can drift, halfway through, toward the person praying beside us. A lesson that began for Allah can drift toward winning the discussion. The cure taught by the hadith’s own principle is to drag the heart back: the moment we notice the drift, we intend again. The deed is long, but the intention can be renewed in an instant, and each renewal is itself an act of honesty with Allah.

Prefer hidden deeds where the deed allows it. A charity no one knows about, a prayer no one sees, a kindness never mentioned — these are training grounds for the heart, because a deed nobody applauds can only have been done for Allah. This is closely tied to good character in Islam, much of which is practised at home, unnoticed and unthanked.

Check the heart when praise arrives. Praise itself is not something we can always prevent, but it is a moment of testing: did the deed quietly change its owner when people began to watch? The humble heart hands the deed back to Allah; learning humility in Islam helps a believer enjoy neither credit nor display.

Ask the question before sharing. Much of modern life is lived in public, including good deeds and beneficial knowledge shared online. Before posting, the hadith’s own logic asks one question: what have I intended? If the honest answer is Allah and benefit for others, share it and move on without watching the response. If the honest answer is applause, the deed can still be rescued — by correcting the intention before the deed is done.

6. When the Intention Slips: Returning, Not Despairing

Every believer’s intention slips sometimes. A prayer begins for Allah and ends with a glance at who noticed. A donation is made sincerely and then mentioned once too often. The teaching of these texts is not despair — it is honesty followed by return. The Prophet ﷺ said: “A man will be rewarded only for what he intended.” (Sahih Muslim 1907a — Sahih) Precisely because reward follows intention so exactly, examining and correcting the intention is worthwhile at every stage: before the deed, during it, and even after it, by turning back to Allah in repentance (tawbah) for the showing-off that crept in.

There is also a quiet comfort in Bukhari’s wording. Allah promises that “every person will get the reward according to what he has intended” (Sahih al-Bukhari 1 — Sahih) — which means the small, hidden, sincerely-meant deed is never at a disadvantage against the large public one. A coin given purely for Allah, a short prayer prayed purely for Allah, a kind word said purely for Allah: each carries the full weight of what was intended. Ikhlas is the door through which ordinary deeds become great.

The straight religion, as the verse calls it, is worship of Allah with submission made exclusive for Him. Guard the intention, and the deeds — great and small — will be guarded with it.

Frequently Asked Questions

Q1. What does ikhlas mean in Islam? Ikhlas means sincerity: worshipping Allah while “making their submission exclusive for him with no deviation” (Quran 98:5) — directing the deed to Allah alone, with no share of it aimed at people’s praise or reward.

Q2. What did the Prophet ﷺ say about intentions? He ﷺ said: “The reward of deeds depends upon the intentions and every person will get the reward according to what he has intended.” (Sahih al-Bukhari 1 — Sahih) This is the first hadith of Sahih al-Bukhari, narrated by Umar ibn al-Khattab.

Q3. Can two people do the same deed and receive different rewards? Yes. The Prophet ﷺ taught that “(The value of) an action depends on the intention behind it. A man will be rewarded only for what he intended.” (Sahih Muslim 1907a — Sahih) His example was emigration: the same journey counted as being for Allah, or for a worldly gain, according to each traveller’s intention.

Q4. Do Salah and Zakah also require sincerity? Yes. The command to make submission exclusive for Allah is given in the same verse that says “to establish Salāh and pay Zakāh” (Quran 98:5) — the outward deeds of prayer and charity are to be filled with inward sincerity.

Q5. What does a person get if he performs a deed for a worldly goal? He gets what he aimed at — the worldly thing itself — rather than the reward of a deed done for Allah. As the Prophet ﷺ said of the emigrant who travelled for worldly benefits or marriage: “his emigration was for what he emigrated for.” (Sahih al-Bukhari 1 — Sahih) This is why renewing the intention toward Allah matters so much.
