Is it permissible to obtain a project through friendship with the manager without paying a bribe, and is the money resulting from it lawful (halal) or unlawful (haram)?

The fundamental principle regarding projects offered as tenders is that they should be awarded to the one with the best quality and price. If the manager favors his friend over this criterion, he has betrayed his trust, and it is not permissible for the friend to accept this offer because he is not the most deserving. The money earned from this project is lawful if the conditions and specifications are met; otherwise, what is taken without work in return or without the stipulated quality is unlawful and must be returned.
