It is narrated from Sayyiduna Anas (may Allah be pleased with him) that a slave-girl was found with her head crushed between two stones. She was brought to the Prophet (peace and blessings be upon him) and was asked: Who did this to you? So-and-so? So-and-so? Until the Jew was named, and she (the slave-girl) gestured with her head. The Jew was summoned and he confessed. The Prophet (peace and blessings be upon him) ordered that his head too be crushed between two stones.
