" From early times it has been taught that the penalty for the apostasy of any individual from Islam is death. There does not seem to be any Qur'anic authority for this extreme form of punishment, one which allows a Muslim no degree of freedom to discover the true revelation of God independently for himself. The Hadith, however, openly state that Muhammad demanded the death sentence for those who turn their backs on Islam, whether for another faith or not. "

It is not wise to publicise details of a Muslim becoming a Christian, the threats against them are very real.
