Qaza'ah (may Allah have mercy on him) says that once Abdullah ibn Umar (may Allah be pleased with them both) sent me on an errand and said, "Come close so that I may bid you farewell in the same manner as the Prophet (peace and blessings be upon him) bid me farewell when he sent me on an errand." Then he took my hand and said, "I entrust your religion, your trustworthiness, and the outcome of your deeds to Allah."
