Are loans provided by a company that acts as an intermediary between mobile networks and users, which involve the repayment of the borrowed amount plus a percentage as profit for the company, considered forbidden usury (riba), and is working for this company and earning a salary from it unlawful?

Lending money to a user with the condition of an increase upon repayment, whether at the time of charging (the account) or when placing it in their wallet, is usury (riba), which is forbidden by consensus. Naming this increase a "company profit," "fee," or "service charge" does not change its nature, for a loan stipulated with an increase is usury.

The only exception is the actual cost of the lending process (such as the cost of paper or an employee's wage), and this cost must be a fixed amount, not a percentage, with no room for profit, as a loan is an act of charity and benevolence. Any increase beyond the actual cost, no matter how small, is usury.

Therefore, it is not permissible to work for a company that engages in this type of usurious transaction.
