Mishkat al-Masabih 4261

Al-Fujai' al-'Amiri told that he came to the Prophet and asked what animals which had died a natural death might be eaten. He asked what they ate, and on receiving the reply niaghtabiq wa-nastabih, which was explained to Abu Nu'aim by 'Uqba as meaning that they drank a cup in the morning and a cup in the evening, he said, "That, by my father, is hunger," and permitted them in such circumstances to eat what had died a natural death. Abu Dawud transmitted it.
