Muwatta Malik: Book 41, Hadith 1

Malik related to me from Nafi that Abdullah ibn Umar said, “The Jews came to the Messenger of Allah, may Allah bless him and grant him peace, and mentioned to him that a man and woman from among them had committed adultery. The Messenger of Allah, may Allah bless him and grant him peace, asked them, ‘What do you find in the Torah about stoning?’ They said, ‘We make their wrong action known and flog them.’ Abdullah ibn Salam said, ‘You have lied! It has stoning for it, so bring the Torah.’ They spread it out and one of them placed his hand over the ayat of stoning. Then he read what was before it and what was after it. Abdullah ibn Salam told him to lift his hand. He lifted his hand and there was the ayat of stoning. They said, ‘He has spoken the truth, Muhammad. The ayat of stoning is in it.’ So the Messenger of Allah, may Allah bless him and grant him peace, gave the order and they were stoned . ”

Abdullah ibn Umar added, “I saw the man leaning over the woman to protect her from the stones.”

Malik commented, “By leaning he meant throwing himself over her so that the stones fell on him.”
