From Sahih Muslim (Hadith 3998):
Abu Huraira (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying:There was a person who gave loans to the people and said to his men: When an insolvent comes to you show him leniency that Allah may overlook our (faults). So when he met Allah, He overlooked his faults (forgave him)
