It is narrated from Hayyaj bin Imran al-Burjumi (may Allah have mercy on him) that a slave of his father had run away, so he vowed to Allah, the Mighty and Majestic, that if he got hold of him he would cut off his hand. When he came to Sayyiduna Imran bin Husayn (may Allah be pleased with him), he said: Tell your father not to do so, "for I heard the Messenger of Allah (peace and blessings be upon him) urging charity in his sermons and forbidding mutilation." Tell your father to make expiation for his oath and to overlook the fault of his slave.
