وَعَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «مَنْ أَنْظَرَ مُعْسِرًا أَوْ وَضَعَ عَنْهُ أَنْجَاهُ اللَّهُ مِنْ كُرَبِ يَوْمِ الْقِيَامَة» . رَوَاهُ مُسلم
He told of hearing God’s Messenger say, “He who grants a respite to one who is in straitened circumstances or who remits his debt will be saved by God from the anxieties of the day of resurrection.” Muslim transmitted it.
