It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that once Sayyiduna Sa'b bin Jaththamah (may Allah be pleased with him) presented the leg of a donkey to the Prophet (peace and blessings be upon him), but the Prophet (peace and blessings be upon him) returned it saying, "We are in the state of Ihram," and at that time blood was dripping from it.
