Abu Waqid al-Laithi told that a man said, "Messenger of God, we live in a land where we are afflicted by hunger, so when may we eat animals which have died a natural death?" He replied, "As long as you do not have a morning drink or an evening drink or gather vegetables you may eat them," meaning that when you do not find a morning drink or an evening drink, or find a vegetable to eat, animals which have died a natural death are allowable to you.
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.
Ibn 'Abbas reported God’s messenger as saying, "Good comes more quickly to the house in which food is provided than the knife comes to the camel's hump." 1
1. This tradition speaks of a hospitable house, the camel’s hump is mentioned because it is the first part of the animal from which meat is cut off, as it is considered the most pleasant part of its meat.
