What happens to Muslims who leave Islam?

Leaving Islam carries no worldly punishment. A person who leaves the faith keeps their life, their property, their dignity, and their place in their family. The Quran’s ruling is clear: “There is no compulsion in religion” (Quran 2:256). Faith that Allah accepts is faith freely given, and a belief held out of fear is worth nothing in His sight.

This answer is for families who are grieving a loved one’s choice, and for those who are questioning or have already left. Allah has kept the matter of faith between Himself and each soul.

What does the Quran say about leaving Islam?

The Quran speaks of people leaving the faith many times, and each time it leaves their judgment to Allah. It never sets a worldly penalty. It addresses freedom of belief directly:

وَقُلِ ٱلۡحَقُّ مِن رَّبِّكُمۡۖ فَمَن شَآءَ فَلۡيُؤۡمِن وَمَن شَآءَ فَلۡيَكۡفُرۡ

“Say: the truth is from your Lord. So whoever wills, let him believe, and whoever wills, let him disbelieve.”

Quran 18:29

Allah also reminds His Prophet ﷺ that conviction cannot be forced, even by a prophet:

أَفَأَنتَ تُكۡرِهُ ٱلنَّاسَ حَتَّىٰ يَكُونُواْ مُؤۡمِنِينَ

“Would you then compel people until they become believers?”

Quran 10:99

Sūrat al-Nisāʾ describes people who “believed, then disbelieved, then believed, then disbelieved” (4:137). The verse assumes that such people go on living among the community long enough to change their minds again and again, and it leaves their reckoning to Allah. Sūrat al-Māʾida says that if some turn away from their religion, Allah will bring a people He loves and who love Him (5:54). Neither verse calls for anyone to be harmed.

How did the Prophet ﷺ treat people who left?

A Bedouin once pledged his allegiance to the Prophet ﷺ in Medina, then fell ill with a fever and came back three times asking to be released from his pledge. Each time the Prophet ﷺ declined to release him, and the man finally left the city. No one pursued him or harmed him (Sahih al-Bukhari 7211).

In the Treaty of Ḥudaybiya (628), the Prophet ﷺ agreed that a Muslim who left Medina and returned to Mecca would not be sent back (Sahih Muslim 1784). The treaty let people walk away from the community without pursuit.

What about the hadith on killing apostates?

A report in Sahih al-Bukhari (6922) says, “Whoever changes his religion, kill him.” The scholars differed (ikhtalafa al-ʿulamāʾ) on how to read it. Most classical jurists took it as a general penalty, and that stricter view is still taught in some places.

Many scholars, classical and modern, read it otherwise. The report is a single-chain (āḥād) narration, and it must be read alongside the Quran’s many verses on freedom of belief. In the Prophet’s ﷺ time, leaving the community usually meant joining its enemies in war. The Hanafi school itself held that a woman who leaves Islam is not executed, because the penalty was tied to men who could take up arms against the community. On this reading the crime was treason and armed rebellion, and belief alone was never punished.

The early Kufan jurist Ibrahim al-Nakhaʿī (d. 714) taught that a person who leaves Islam is invited to return for the rest of their life, and Sufyan al-Thawri (d. 778) is reported to have held the same view. An invitation that lasts a lifetime leaves no room for execution. In the twentieth century, Mahmud Shaltut, Grand Imam of al-Azhar (1958–1963), argued that many scholars do not establish fixed penalties on single-chain reports, and that unbelief alone does not make a person’s blood lawful. Taha Jabir al-Alwani’s Apostasy in Islam (2011) showed that the Quran and Sunnah contain no explicit evidence for punishing a person whose only act is a change of faith. The Sudanese scholar Abdullahi An-Na’im has argued that belief has value only when it is free. The stronger view, and the one that fits the Quran, is that apostasy has no worldly punishment.

What should families do when someone leaves Islam?

Grief is natural when a beloved child or sibling leaves the faith you treasure. Keep that grief in prayer, and keep your love in your actions. The Quran commands a child to keep company with their parents “in this world with kindness” even when the parents urge them toward shirk (31:15). When Asmāʾ bint Abī Bakr’s mother, who still worshipped idols, came to visit her, the Prophet ﷺ told Asmāʾ, “Keep the bond with your mother” (Sahih al-Bukhari 2620).

The same applies when the child is the one who left. Cutting off a son or daughter, threatening them, or shaming them in the community is haram, as explained in Is it permissible to disown your child? and Is it haram to harass people about religion?. Keep them at the family table. Many who leave come back in time, and they return through the door that love kept open.

What if I am questioning my faith or have left?

Questions are part of human life, and many great scholars wrestled with doubt before they found certainty. Imam al-Ghazali (d. 1111) describes in his autobiography, al-Munqidh min al-Ḍalāl, a period of deep doubt that lasted about two months. You do not need to hide your questions from Allah. He already knows them.

If you have left, your life and safety are sacred. No one has the right to threaten you, and if anyone does, contact your local police. Your final destiny belongs to Allah, whose mercy embraces all things (7:156), and who judges each person by what they truly knew and could understand. The article Do non-Muslims go to hell? explains how wide that mercy is.

A closing prayer

The Quran teaches believers a prayer for steadfastness that every heart can make its own:

رَبَّنَا لَا تُزِغۡ قُلُوبَنَا بَعۡدَ إِذۡ هَدَيۡتَنَا وَهَبۡ لَنَا مِن لَّدُنكَ رَحۡمَةًۚ إِنَّكَ أَنتَ ٱلۡوَهَّابُ

“Our Lord, do not let our hearts turn away after You have guided us, and grant us mercy from Yourself. You are the Giver.”

Quran 3:8

May Allah keep every family together in love, and guide every searching heart to what is true and good.
