Is it permissible for the questioner's father, who owns a contracting company, to take a monthly financial return from workers (whether newly recruited or those whose sponsorship has been transferred) who work for themselves, even if this is a small, agreed-upon percentage?

The Council of Senior Scholars issued a resolution stating that bringing in workers and employing them with parties other than the original sponsor, while the sponsor takes a portion of their wages or a known amount from them, is forbidden and unlawful. This is due to its violation of the general regulations established by the state, the obligation to obey the ruler in what is good, and the great corruption and evil that results from it. However, if a person brings in workers to work for him at a certain price, and then leases them to another party at a higher price and takes the difference, there is no harm in that if the workers agree. The difference belongs to the first employer if the worker consents.
