وَعَنْ أَبِي الْيَسَرِ قَالَ: سَمِعْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «مَنْ أَنْظَرَ مُعْسِرًا أَوْ وَضَعَ عَنْهُ أَظَلَّهُ اللَّهُ فِي ظِلِّهِ» . رَوَاهُ مُسلم

Abul Yasar told of hearing God’s Messenger say, “He who grants a respite to one who is in straitened circumstances or remits his debt will be taken by God under His protection.” Muslim transmitted it.
