From Sahih Muslim (Hadith 3995):
Hudhaifa (Allah be pleased with him) reported Allah's Apostle (ﷺ) as saying:A person died and he entered Paradise. It was said to him What (act) did you do? (Either he recalled it himself or he was made to recall), he said I used to enter into transactions with people and I gave respite to the insolvent and did not show any strictness in case of accepting a coin or demanding cash payment. (For these acts of his) he was granted pardon. Abu Mas'ud said: I heard this from Allah's Messenger (ﷺ)
