- Apostasy occurs not only when a Muslim renounces Islam but also, among other things, when a Muslim appears to worship an idol,
when he is heard "to speak words that imply unbelief,"
when he makes statements that appear to deny or revile Allah or the prophet Mohammed,
when he is heard "to deny the obligatory character of something which by consensus of Muslims is part of Islam,"
and when he is heard "to be sarcastic about any ruling of the Sacred Law"
