All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah and that Muhammad, sallallaahu ʻalayhi wa sallam, is His slave and Messenger.
There is a difference between the administrative fees charged in return for loan processing and the interest payable by the debtor beyond the actual loan itself, even if it is given a different name. If this money consists of actual administrative fees, then there is no harm in paying them. The Council of the Islamic Fiqh Academy, in its third session, has resolved that "it is permitted to charge a fee for loan-related services. However, this fee should be within the limits of actual expenses, and any fee in excess to actual service-related expenses is forbidden because it is considered usurious interest (riba)." [End of quote]
According to the previously underlined resolution of the Council of the Islamic Fiqh Academy, the criterion for distinguishing between actual administrative fees and usurious interest is that the charged fees should be within the estimated administrative expenses of the provided loan services and not more.
As for the inflation or the small percentage of the interest, both factors are irrelevant in this regard and do not entail deeming dealing with usury allowable. Dealing with usury is permitted only in case of a real and sharee'ah-acceptable necessity; and, verily, whoever fears Allaah, He will make for him a way out of his problem and provide for him from (sources) he could not have imagined.
Allaah knows best.
