Is it permissible to take a monthly percentage from teachers' salaries in exchange for providing job opportunities for them, and what are the Sharia conditions related to that?

It is permissible to agree with students to teach them the Quran and Arabic language for a financial fee, and it is permissible to agree with a subcontractor teacher to teach them for a lower fee, and to benefit from the difference. The contract is between the center and the students, and there is no need to inform the teacher of the agreement concluded with the students. If the center's role is merely to introduce the teacher to the students, then it is a brokerage contract whereby the center is entitled to a one-time commission. However, if the center continues to manage and organize the work, then it is entitled to a monthly commission.
