Taking a commission for the businesses done by paying a bribe
What the abovementioned person does is prohibited bribery. He who pays it and the intermediary are cursed. Thus, you have to advise him not to do it again. Moreover, it is impermissible for you to
accept projects he obtains in return for these bribes as it falls under helping one another in sin (Part No. 23; Page No. 569) and transgression and consuming people's property unjustly.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
