"The Prophet -- the blessing and peace of Allah be upon him -- said, "He who changes his religion must be killed"; this holds true both for men and women. The apostasy of a man calls for putting him to death. It is unanimously agreed upon that apostasy is a horrible crime deserving a horrible punishment. The apostasy of a woman is no less horrible. Therefore, it too deserves a corresponding punishment: death." - Abdurrahmani'l-Djaziri
