Sunan Ibn Majah Book 15, Hadith 28
Whoever is easy with (a debtor) who is in difficulty, Allah will be easy with him in this world and in the Hereafter.”
“Whoever leaves behind money, it is for his heirs, and whoever leaves behind a debt for children, I am nearer to the believers.”
“Whoever gives respite to one in difficulty, he will have (the reward of) an act of charity for each day. Whoever gives him respite after payment becomes due, will have (the reward of) an act of charity equal to (the amount of the loan) for each day.”
