A hadith like this is narrated on the authority of Abu Huraira (Allah be pleased with him).
Sahih Muslim Book 22, Hadith 38
← Previous Hadith 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).

Sahih Muslim Book 22, Hadith 37 Next Hadith → I am hard up financially, whereupon he said: (Do you state it) by God? He said: By God. Upon this he (Qatada) said: I heard Allah's Messenger (ﷺ) as saying: He who loves that Allah saves him from the torments of the Day of Resurrection should give respite to the insolvent or remit (his debt).

Sahih Muslim Book 22, Hadith 39
