Abu Sa'id al-Khudri told th at they said, “Messenger of God, we cut the throat of a she-camel and slaughter a cow and a sheep and find an embryo in its womb. Shall we throw it away or eat it?” He replied, “Eat it if you wish, for its slaughter is included when its mother is slaughtered.”
‘Abdallah b. ‘Amr b. al-‘As reported God’s messenger as saying, “If anyone kills a sparrow or anything greater wrongfully God will question him about killing it.” On being asked what was the right way he replied, “To cut its throat and eat it, but not to cut off its head and throw it away.”
Ibn ‘Abbas and Abu Huraira said God's messenger forbade the devil’s sacrification. Ibn Isa* added that this refers to the slaughtered animal whose skin is cut off and is then left to die without its jugular veins being severed.
