Abdullah bin Amir bin Rabi'ah (may Allah be pleased with him) says: I saw Sayyiduna Uthman bin Affan (may Allah be pleased with him) at al-Arj on a hot summer day while he was in the state of ihram, and he had covered his face with a red velvet wrap. Then some game meat was brought, and he said to his companions: Eat. His companions said: Will you not eat? He said: I am not like you, for it was hunted only on my account.
