Though Allah stated that the punishment for adultery should be 100 lashes (Quran 24:2), Muhammad decided to have an adulteress stoned to death, as we read here:
'Allah's Messenger (may peace he upon him) said: By Him in Whose Hand is my life. I will decide between you according to the Book of Allah. The slave-girl and the goats should be given back, and your son is to be punished with one hundred lashes and exile for one year. And, O Unais (b. Zuhaq al-Aslami), go to this woman in the morning, and if she makes a confession, then stone her. He (the narrator) said: He went to her in the morning and she made a confession. And Allah's Messenger (may peace be upon him) made pronouncement about her and she was stoned to death.'" (from Sahih Muslim, 17:14209).
We know that Muhammad is the role model for the Muslims (see Quran 33:21). Thus it can be no surprise that members of the Islamic State similarly stone an adulteress to death:
Could Allah have been clearer about what he wanted as punishment for adultery? If Allah had dissuaded Muhammad from stoning the adulteress, would ISIS have had any reason to stone the woman featured in the video above?
Do you believe that stoning someone to death for adultery is proper?
