Maliks Muwatta Book 41, Hadith Number 3.

Section : Stoning.

Malik related to me from Yahya ibn Said that Said ibn al-Musayyab said, “I have heard that the Messenger of Allah, may Allah bless him and grant him peace, said to a man from the Aslam tribe called Hazzal, ‘Hazzal, had you veiled him with your cloak, it would have been better for you.'”

Yahya ibn Said said, “I related this hadith in an assembly among whom was Yazid ibn Nuaym ibn Hazzal al-Aslami. Yazid said, ‘Hazzal was my grandfather. This hadith is true.'”
