Narrated Anas:
A Jew crushed the head of a girl between two stones. The girl was asked who had crushed her head, and some names were mentioned before her, and when the name of the Jew was mentioned, she nodded agreeing. The Jew was captured and when he confessed, the Prophet ordered that his head be crushed between two stones.
