Musannaf Ibn Abi Shaybah 22304 — A man who lends a loan to another

Ibrahim (may Allah have mercy on him) said: If a man is owed some dirhams as a loan by another man, and he comes to him and demands repayment, and the debtor says: Keep in exchange for it barley, wheat, dates or anything other than gold, there is no harm. When his dirhams are a loan owed by the other, he may take from him in exchange whatever he wishes.
