Sahih Muslim 1563 a
Abdullah b. Abu Qatada reported that Abu Qatada (Allah be pleased with him) demanded (the payment of his debt) from his debtor but he disappeared; later on he found him and he said:
I am hard up financially, whereupon he said: (Do you state it) by God? He said: By God. Upon this he (Qatada) said: I heard Allah's Messenger (ﷺ) as saying: He who loves that Allah saves him from the torments of the Day of Resurrection should give respite to the insolvent or remit (his debt).
حَدَّثَنَا أَبُو الْهَيْثَمِ، خَالِدُ بْنُ خِدَاشِ بْنِ عَجْلاَنَ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ أَيُّوبَ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ، أَنَّ أَبَا قَتَادَةَ، طَلَبَ غَرِيمًا لَهُ فَتَوَارَى عَنْهُ ثُمَّ وَجَدَهُ فَقَالَ إِنِّي مُعْسِرٌ ‏.‏ فَقَالَ آللَّهِ قَالَ آللَّهِ ‏.‏ قَالَ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏
"‏ مَنْ سَرَّهُ أَنْ يُنْجِيَهُ اللَّهُ مِنْ كُرَبِ يَوْمِ الْقِيَامَةِ فَلْيُنَفِّسْ عَنْ مُعْسِرٍ أَوْ يَضَعْ عَنْهُ ‏"‏ ‏.‏
