A:
If the case is as mentioned, and it is offered as a good gesture, there is nothing wrong with this whether it is brought by the guilty, the victim, or a third party. Whereas if it is offered as a penalty, this is to be considered Ta`zir (discretionary punishment) through paying money (the costs of the banquet), and this requires the stipulation of a legal ruler, but there is no harm in it as long as the person offers willingly. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
