Is the mediation process that takes place between two parties (creditor and debtor), whereby the mediator receives a percentage of the amount owed to the creditor, and agrees with the debtor (or their representatives) on a portion of this amount to facilitate the payment process, with the knowledge and consent of the creditor, considered a bribe?

Using one's influence and connections to help someone obtain their rightful due is a permissible and commendable act, and it may even become obligatory if it is the only means, based on the hadith: "Support your brother whether he is an oppressor or oppressed." Receiving payment for this (the price of influence) is a matter of scholarly disagreement. If payment is permissible, it must be a known amount, either a fixed sum or a specified percentage of a known amount. However, if it is a percentage of an unknown amount, then the payment is unknown, and the person with influence is entitled to the customary wage (ajrat al-mithl). If the person with influence is a guardian who is obligated to perform this act, then giving them anything for their work is considered illicit gain (suht) and bribery. As for the rightful owner relinquishing part of their right in exchange for facilities, one must stand with the oppressed until they receive their full right or relinquish it willingly. If the relinquishment is due to coercion, it is an unjust settlement and an oppression from which the other party is not permitted to take anything, even if contentment appears outwardly, because it is often a result of coercion.
