I heard the Messenger of Allah ﷺ say: “Allah will shade with His shade on the Day when there is no shade but His a person who gave more time to a debtor who was in difficulty or waived a debt for one who had a lot of debts.ʿ (Using translation from Aḥmad 532)
"أَظلَّ الله عبْدًا في ظِلِّهِ يَوْمُ لا ظِلَّ إلَّا ظِلُّه: أنْظَر مُعْسِرًا أوْ تَرَكَ لغِارمٍ".
