Sahih Bukhari Volume 009, Book 083, Hadith Number 016.
Narrated By Anas bin Malik : A girl wearing ornaments, went out at Medina. Somebody struck her with a stone. She was brought to the Prophet while she was still alive. Allah's Apostle asked her, "Did such-and-such a person strike you?" She raised her head, denying that. He asked her a second time, saying, "Did so-and-so strike you?" She raised her head, denying that. He said for the third time, "Did so-and-so strike you?" She lowered her head, agreeing. Allah's Apostle then sent for the killer and killed him between two stones.
