Musnad Ahmad

Abdullah bin Al-Harith narrates that his father Harith was responsible for the food of Sayyiduna Uthman (may Allah be pleased with him). Abdullah bin Al-Harith says that the scene is still vivid in my eyes: around the pots was placed horse meat. A man came and said that Sayyiduna Ali (may Allah be pleased with him) does not consider it good. Sayyiduna Uthman Ghani (may Allah be pleased with him) sent for him. Sayyiduna Ali (may Allah be pleased with him) came, dusting off his hands. Sayyiduna Uthman (may Allah be pleased with him) said to him, "You differ with us a lot." Hearing this, Sayyiduna Ali (may Allah be pleased with him) said, "I swear by every person who was present at that time in the service of the Prophet (peace and blessings be upon him), when the haunch of a wild donkey was brought to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said, 'We are in the state of Ihram, feed this to the people of Hil.' Is this not so?" Upon this, some of the companions (may Allah be pleased with them) of the Prophet (peace and blessings be upon him) stood up and confirmed Sayyiduna Ali (may Allah be pleased with him). Then Sayyiduna Ali (may Allah be pleased with him) said, "When five ostrich eggs were brought to the Prophet (peace and blessings be upon him), I ask those companions (may Allah be pleased with them) present at that time by oath, did the Prophet (peace and blessings be upon him) not say, 'We are in the state of Ihram, feed these to those who are not in Ihram'?" Upon this, some companions (may Allah be pleased with them) stood up. Seeing this, Sayyiduna Uthman (may Allah be pleased with him) got up from the dining mat and went to his tent, and that food was eaten by the people of Ma’.
