Is the brother who works in a supervisory capacity over construction companies sinful for interceding to secure his brother a job in one of the companies he oversees, and then they—in addition to their third brother—undertake finishing works for that company and similar companies?

There is no objection, we hope, for the brothers to participate with their brother in his contracting work, as long as the agreed-upon wage with the companies is similar to the wage of an ordinary contractor, and there is no favoritism for the brother in it. It is stipulated that the employee’s undertaking of these works must be lawful, with the company's permission and a valid lease contract. If one of the partners is responsible for the finishing work, then further permission from his company is required; because an agent selling to himself is not permissible, especially when there is an accusation of favoritism. However, if he undertakes it unlawfully and with favoritism, then it is a bribe, and it is not permissible for the brothers to accept it or assist in it.
