Ibn Jurayj (may Allah have mercy on him) says: I said to Ata (may Allah have mercy on him): "Then the compensation is the like of what he killed, from livestock" up to "an offering brought to the Ka'bah, or an expiation: the feeding of needy people" [Surah al-Ma'idah: 95]. He said: Because he did this within the Haram, the expiation too is to be paid at the House of Allah.
