Sunan Ibn Majah Book 15, Hadith 43
“I asked Anas bin Malik: 'What if a man gives his brother a loan, then (the borrower) give him a gift?’ The Messenger of Allah (ﷺ) said: ‘If anyone of you borrow something then he gives (the lender) a gift or gives him a ride on his riding-beast, he should not accept the gift or the ride, unless they used to treat each other in that manner beforehand.'”
“On the night on which I was taken on the Night Journey (Isra), I saw written at the gate of Paradise: 'Charity brings a tenfold reward and a loan brings an eighteen fold reward.' I said: 'O Jibril! Why is a loan better than charity?' He said: 'Because the beggar asks when he has something, but the one who asks for loan does so only because he is in need.' ”
his brother died, leaving behind three hundred Dirham and dependents. “I wanted to spend (his money) on his dependents, but the Prophet (ﷺ) said: 'Your brother is being detained by his debt, so pay it off for him.'” He said “O Messenger of Allah (ﷺ), I have paid it off apart from two Dinar, which a woman is claiming but she has no proof.” He said: “Give them to her for she is telling the truth.”
