Hadith 8:140
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.
وَعَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «مَنْ أَنْظَرَ مُعْسِرًا أَوْ وَضَعَ عَنْهُ أَنْجَاهُ اللَّهُ مِنْ كُرَبِ يَوْمِ الْقِيَامَة» . رَوَاهُ مُسلم
