Is the sum of money that the brother-in-law will pay to the friend of the brother, which the friend requested under the pretext of a debt after the transaction is completed, considered a bribe?

The jurists differed regarding the ruling on taking compensation for exerting influence (utilizing one's position or connections to facilitate a matter). Some absolutely prohibit it, while others absolutely permit it. Still others elaborate on the matter, permitting it if the effort involved hardship and expense, with the payment estimated based on the customary wage or agreed upon beforehand as a known fee, or if the matter is based on leniency.
