Sa’id bin Mansur reported that commenting on the words of Allah “the compensation is an offering, brought to the Ka’bah, of a domestic animal” Ibn ‘Abbas said: “If a muhrim kills an animal, an assessment should be made and then he should make compensation. If he has an animal of an equivalent value for the game, he must slaughter it and give its meat in charity, but if he does not have an animal of an equivalent value, he should assess the value of the game and then give away food for that amount. In case one does not have money for it, then, one must fast one day for each half sa’ of food. If a muhrim killed a game, he must slaughter a similar animal according to the judgment of two just men. If one killed a deer or similar animal, one must slaughter a sheep in Makkah. If one cannot buy a sheep, then, one must feed six poor people, and if one cannot afford that, then one must fast three days.
If one killed a male adult deer or similar animal, he must slaughter a cow, otherwise one must feed twenty needy people, or fast for twenty days. If an ostrich or zebra or similar animal is killed, one must fast thirty days. This is reported by Ibn Abi Hatem and Ibn Jarir. They also added to this the words: “The food given to the needy must be sufficient to satisfy their hunger.”
