Hadith 8:139
Abu Qatada reported God's Messenger as saying, “If anyone would like God to save him from the anxieties of the day of resurrection, he should grant a respite to one who is in straitened circumstances, or remit his debt.” Muslim transmitted it.
وَعَنْ أَبِي قَتَادَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ سَرَّهُ أَنْ يُنْجِيَهُ اللَّهُ مِنْ كُرَبِ يَوْمِ الْقِيَامَةِ فَلْيُنَفِّسْ عَنْ مُعْسِرٍ أَوْ يَضَعْ عَنْهُ» . رَوَاهُ مُسْلِمٌ
