Muhammad Rasheed - The Qur'an says that "there is no compulsion in religion," so anyone claiming that Allah orders other Muslims to kill the leaver is out of line. We are not allowed to punish people who decide that Islam isn't for them, and Muslim theocratic governments who make laws that have such punishments within them are not doing so from an Islamic position at all.
O ye who believe! Stay your hand, and sheathe your swords! Attack not the transgressor of faith lest he should attack you. It may be that it is Allah's will that the transgressor will soften his heart and turn back to the Truth. The future lies in the unseen, and Allah has not shared the secrets of the unseen with you! Will you not then be wise? Peace.
