It is narrated from Sayyiduna al-Bara' bin Azib (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) camped at Zahran (Marr al-Zahran), and a limb of a hunted animal was presented to him (peace and blessings be upon him) as a gift. He (peace and blessings be upon him) returned it to the one who had brought it and said to him: "Convey my greetings of peace to him and say: Were we not in the state of ihram, we would not have returned it to you."
