no rational person would sell one dirham for another identical dirham on deferred payment.

Accordingly, a loan is an act of kindness and voluntary assistance, not a compensatory exchange. For this reason the Prophet ﷺ called it a “grant” (manīḥa): the borrower benefits from it and then returns the very same item; if that is impossible, he returns its equivalent or something of the same kind.

Sharḥ al-Iqnāʿ states, “It is among the recommended forms of facilitation for the lender,” citing the Prophet’s ﷺ words: “Whoever relieves a believer of a hardship of this world, Allah will relieve him of a hardship on the Day of Resurrection” (Muslim 2699).

Because of the great reward it entails, Anas reported that the Prophet ﷺ said: “On the night I was taken up, I saw written on the gate of Paradise: Charity is rewarded tenfold, while a loan is rewarded eighteenfold. I asked, ‘O Gabriel, why is a loan better than charity?’ He replied, ‘Because the beggar may ask while still possessing something, whereas the borrower seeks a loan only out of genuine need’” (Ibn Mājah 2431).

Thus, borrowing does not belong to the censured forms of asking, since the Prophet ﷺ himself did it. Nor is there any sin on one who is asked to lend but chooses not to, for lending is recommended, not obligatory.
