What does the Quran say about apostasy?
The Quran warns apostates, except those who later repent, that a severe and painful punishment awaits them in the afterlife.They shall forever be the companions of hellfire, the holy book says.But nowhere in the Quran does God command earthly authorities to execute anyone who has converted from Islam.That omission is key, because the Quran says, “The Lord neglects nothing, nor does he forget.”
In other words, if God wanted apostates killed, he would have said so.
Instead, the Quran’s message is: The apostate is accountable to Allah in the hereafter, not to judges on Earth.As one passage says, “It is God who judges.”
What did Mohammed say about apostasy?
Unlike the Quran, there are conflicting stories and opinions about the prophet’s stance on apostasy. According to several sayings attributed to him in the Sunna, Mohammed did call for apostates to be killed. “He who changes his religion, kill him,” the prophet said, according to one hadith, or story about his life.
But other stories contradict that teaching. In the seventh century, for example, Mohammed, as leader of the growing Muslim community, brokered a truce with the Qurayshites, a competing religious tribe. In the Truce of Hudaybiyyah, Mohammed agreed that if any Qurayshite came to join the Muslim community, he would not accept them.
On the other hand, Muslims were permitted to join the Qurayshites, no questions asked, no executions threatened. Moreover, lots of Muslim coverts abandoned Islam during the prophet’s life, and he never sentenced one to death. The Sahih al-Bukhari, one of the most famous collections of Sunna, contains an illustrative example. A Bedouin man pledged allegiance to God and the prophet, only to later inform Mohammed that he wanted to cancel his pledge. After the prophet refused three times to accept his cancellation, the Bedouin simply moved to another town.
The prophet did not order his execution despite such clear and undisputed apostasy. And there are many other examples like this in the Muslim historical literature. The conflicting stories and lessons from Mohammed's life is one reason why the Sunna is not considered as authoritative a source of Islamic law as the Quran.
