Sayyiduna Sa'b bin Jaththamah (may Allah be pleased with him) related that he gave the Messenger of Allah (peace and blessings be upon him) a wild donkey as a gift while he (peace and blessings be upon him) was at Waddan or al-Abwa', and he (peace and blessings be upon him) returned it to him. When he (peace and blessings be upon him) recognised in my face the grief at its being returned, he said: "We did not return it to you out of disregard for you; rather, we are in the state of ihram."
