I run an office that does the work of collecting debts in return for some fees received by the office
after making an agreement with the creditor. Is this permissible? Moreover, some banks ask me to collect their debts in return for a payment. I will not accept this offer until I know the ruling on this act. Am I allowed to make a condition that I receive the payment before or after collecting the debts? Is it permissible for me to set a definite percentage of the basic amount of the debt as my payment? I hope you can answer me. May Allah protect and support you!
There is nothing wrong with receiving a payment for collecting interest-free loans for the creditor. It is impermissible for a Muslim to collect Riba-based loans or to receive a payment for doing this. This is because doing so falls under the category of helping one another in sin and transgression and acknowledging evil. The amount and time of receiving the payment should be determined by the terms agreed on by both parties. The Prophet (peace be upon him) said: (Part No. 14; Page No. 270)
Muslims are bound by their conditions, except such which makes lawful unlawful and unlawful lawful.
May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions!
