Q: My question is about Al-Muqana`ah (Bidders' collusion to offer a low price) in public auctions. What is the ruling on doing it? Some people go to public auctions for the sale of governmental properties and collude to bid a low price for commodities. After the auction, they sell the commodities to one another and distribute the profits on equal terms. May Allah reward you with the best.

A: This practice is not permissible because it involves cooperation in committing sin and transgression. Also, the bidders who collude together are guilty of wronging the owner of the commodity for the sake of their own benefit. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
