What is the ruling on assuming governmental positions through mediation, such as a person joining a governmental job due to his kinship with an official, for example?

The positions of Muslims are public rights, and the appointment of a person to a position must be based on the interest of the work, and the qualified, strong, and trustworthy individual is the one who should undertake it, as Allah Almighty mentioned through the words of Shu'aib's daughter. Any action that contradicts this is considered a betrayal and negligence. As for whoever obtained the position through mediation or money, his wage is lawful, even if the method of obtaining it was incorrect.
