Islam teaches that apostates from Islam must be killed. Even in the West, ex-Muslims often keep their apostasy secret from their own families. Some fear persecution if their rejection of the faith is discovered. Some fear for their lives, knowing that being “honor-killed” by a parent, sibling, or relative is very common in the Muslim world. Is it the sheer terror and brutality of Islam that is causing a tidal wave of apostasy?
Quran (4:89) – “They wish that you reject Faith, as they have rejected (Faith), and thus that you all become equal (like one another). So take not Auliya’ (protectors or friends) from them, until they emigrate in the Way of Allah (to Muhammad). But if they turn back (from Islam), take (hold) of them and kill them wherever you find them.”
