The question in this post is: “Why is it that stoning to death is considered the Islamic punishment for adultery by so many, when it is not mentioned anywhere in the Quran and the punishment for illegal sex (zina) is clearly stated to be 100 lashes?” The reply, given by Sheikh Muhammad Ali Al-Hanooti, states a Muslim believes in the Qur’an and Hadith as two major sources of revelation. If one denies stoning for adultery then he/she is of the people who deny Hadith as a source of Islamic Law, which is used by almost all the schools of Shari’a.
