What the Quran says
لَآ إِكۡرَاهَ فِي ٱلدِّينِۖ قَد تَّبَيَّنَ ٱلرُّشۡدُ مِنَ ٱلۡغَيِّۚ فَمَن يَكۡفُرۡ بِٱلطَّٰغُوتِ وَيُؤۡمِنۢ بِٱللَّهِ فَقَدِ ٱسۡتَمۡسَكَ بِٱلۡعُرۡوَةِ ٱلۡوُثۡقَىٰ لَا ٱنفِصَامَ لَهَاۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌThere shall be no compulsion in [acceptance of] the religion. The right course has become distinct from the wrong. So whoever disbelieves in ṭāghūt and believes in Allāh has grasped the most trustworthy handhold with no break in it. And Allāh is Hearing and Knowing.
وَقُلِ ٱلۡحَقُّ مِن رَّبِّكُمۡۖ فَمَن شَآءَ فَلۡيُؤۡمِن وَمَن شَآءَ فَلۡيَكۡفُرۡۚ إِنَّآ أَعۡتَدۡنَا لِلظَّٰلِمِينَ نَارًا أَحَاطَ بِهِمۡ سُرَادِقُهَاۚ وَإِن يَسۡتَغِيثُواْ يُغَاثُواْ بِمَآءٖ كَٱلۡمُهۡلِ يَشۡوِي ٱلۡوُجُوهَۚ بِئۡسَ ٱلشَّرَابُ وَسَآءَتۡ مُرۡتَفَقًاAnd say, "The truth is from your Lord, so whoever wills - let him believe; and whoever wills - let him disbelieve." Indeed, We have prepared for the wrongdoers a fire whose walls will surround them. And if they call for relief, they will be relieved with water like murky oil, which scalds [their] faces. Wretched is the drink, and evil is the resting place.
The hadith and scholars’ views
مَنْ بَدَّلَ دِينَهُ فَاقْتُلُوهُWhoever changes his religion, kill him.
Most classical jurists held a penalty for the one who openly renounces Islam. Others, among them Ibrahim an-Nakha’i, Sufyan ath-Thawri and some contemporary scholars, held that the hadith concerns the traitor who fights the community, not mere change of belief. It is also reported that a Bedouin asked the Prophet ﷺ to release him from his pledge, and he did not kill him. It is a matter of scholarly reasoning, and no individual may apply it on his own; it is for the judiciary.
Frequently asked questions
Is someone who leaves Islam killed today?
No one may do so on his own; it is disputed and a matter for the judiciary, and many contemporary scholars affirm freedom of belief.
