Sayyiduna al-Fuja'i al-Amiri (may Allah be pleased with him) came to the Prophet (peace and blessings be upon him) and said: What of carrion is lawful for us? He (peace and blessings be upon him) said: "What is your food?" He said: We drink a little in the evening and a little in the morning. He (peace and blessings be upon him) said: "That is hunger." So he (peace and blessings be upon him) made carrion lawful for them in this condition.
Abu Nu'aym said: Uqbah explained it to me thus: a cup in the evening and a cup in the morning.
