O ye who believe! Kill not game while in the sacred precincts or in pilgrim garb. If any of you doth so intentionally, the compensation is an offering, brought to the Ka'ba, of a domestic animal equivalent to the one he killed, as adjudged by two just men among you; or by way of atonement, the feeding of the indigent; or its equivalent in fasts: that he may taste of the penalty of his deed. Allah forgives what is past: for repetition Allah will exact from him the penalty. For Allah is Exalted, and Lord of Retribution. Al-Ma'idah 5:95 ⧉
Tafsir:
The real purpose of this order is that God may know those who fear Him, even if they cannot see Him. God has placed human beings in this world, but has concealed Himself from their eyes. Now, He wants to see who, without seeing Him, is so reality-conscious as to behave righteously, as if he were actually seeing Him with all His powers, unlike those who, not finding God before them, become fearless and behave as they please. This is experienced not only during the short period of the pilgrimage, but also on a daily basis in human relations. A man may gain such control over another that it is quite possible for him to threaten his life, ruin him financially or falsely defame and degrade him. Now, under these conditions, there may conversely be a man who, in spite of having such control and similar opportunity, holds his peace and stays his hands out of fear of God. Of these two, the latter has proved that he fears God without seeing Him, while the former has proved otherwise. The latter has countless divine blessings in store for him, while there shall be a terrible punishment for the former.
