Say idina Abn Hurayrah (RA) reported that Ma’iz Aslami (RA) came to Allah s Messenger (SAW) and said that he had committed adultery. But he turned his face away from him. He came from the other side and said, “I have committed adultery”. He again turned his face away from him. But he come that side and said, “Messenger of Allah (SAW), I have committed adultery’. The fourth time, he gave on order and he was taken to Harrah and was being stoned, when he found the stones striking him, he fled till he come to a man who had a camel’s jawbone in his hand. He struck him with it and the people (also) hit him till he died. They mentioned that to Allah’s Messenger (SAW) saying, “He fled as he felt the stones on him and the touch of death”. Allah’s Messenger (SAW) said “Why did you not spare him?’.
