a man was brought to the Prophet for him to offer the funeral prayer, and he said: "Pray for your companion, for he owes a debt." Abu Qatadah said: " I will pay it." The Prophet said: "In full?" He said: "In full." So he prayed for him (Using translation from Nasāʾī 1960)  

أَنَّ رَسُولَ اللهِ ﷺ أُتِيَ بِرَجُلٍ مِنَ الْأَنْصَارِ لِيُصَلِّيَ عَلَيْهِ فَقَالَ النَّبِيُّ ﷺ «صَلُّوا عَلَى صَاحِبِكُمْ فَإِنَّ عَلَيْهِ دَيْنًا» قَالَ أَبُو قَتَادَةَ هُوَ عَلَيَّ فَقَالَ النَّبِيُّ ﷺ بِالْوَفَاءِ قَالَ بِالْوَفَاءِ قَالَ فَصَلَّى عَلَيْهِ  

"A Janazah was brought to the Prophet and they said: " O Prophet of Allah, pray for him.' He said: "Did he leave any debt behind?' They said: "Yes.' He said 'Did he leave anything?' They said: No. He said; 'Pray fro your companion.' A man among the Ansar who was called Abu Qatadah said: 'Pray for him and I will pay off his debt.' So he prayed for him." (Using translation from Nasāʾī 1961)  

أُتِيَ النَّبِيُّ ﷺ بِجِنَازَةٍ فَقَالُوا يَا نَبِيَّ اللهِ صَلِّ عَلَيْهَا قَالَ «هَلْ تَرَكَ عَلَيْهِ مِنْ دَيْنٍ؟» قَالُوا نَعَمْ قَالَ «هَلْ تَرَكَ مِنْ شَيْءٍ؟» قَالُوا لَا قَالَ «صَلُّوا عَلَى صَاحِبِكُمْ» قَالَ رَجُلٌ مِنَ الْأَنْصَارِ يُقَالُ لَهُ أَبُو قَتَادَةَ صَلِّ عَلَيْهِ عَلَيَّ دَيْنُهُ فَصَلَّى عَلَيْهِ  

"The Prophet would not pray for a man who owed a debt. A deceased person was brought to him and he said: 'Does he owe any debt?' They said: 'Yes, he owes two Dinars.' He said: 'Pray for your companion.' Abu Qatadah said: 'I will pay them, O Messenger of Alllah, So he prayed for him. Then, when Allah made His Messenger rich though conquest, he said: ' I am closer to each believer than his own self. Whoever leaves behind a debt, I will pay it, and whoever leaves behind wealth, it is for his heirs." (Using translation from Nasāʾī 1962)  

كَانَ النَّبِيُّ ﷺ لَا يُصَلِّي عَلَى رَجُلٍ عَلَيْهِ دَيْنٌ فَأُتِيَ بِمَيِّتٍ فَسَأَلَ «هَلْ عَلَيْهِ دَيْنٌ؟» قَالُوا نَعَمْ دِينَارَانِ قَالَ «صَلُّوا عَلَى صَاحِبِكُمْ» قَالَ أَبُو قَتَادَةَ هُمَا عَلَيَّ يَا رَسُولَ اللهِ فَصَلَّى عَلَيْهِ فَلَمَّا فَتَحَ اللهُ عَلَى رَسُولِهِ ﷺ قَالَ «أَنَا أَوْلَى بِكُلِّ مُؤْمِنٍ مِنْ نَفْسِهِ مَنْ تَرَكَ دَيْنًا فَعَلَيَّ وَمَنْ تَرَكَ مَالًا فَهُوَ لِوَرَثَتِهِ»  

if a believer died at the time of the Messenger of Allah ﷺ and he had debts, the Messenger of Allah ﷺ would ask: “Did he leave anything with which to off his debt?” If they said yes, then he would offer the funeral prayer for him, but if they said no, then he would say: “Pray for your companion.” When Allah granted his Prophet ﷺ the conquests, he said: “I am nearer to the believers than their own selves. Whoever dies owing a debt, I will pay it off for him, and whoever leaves behind wealth, it will be for his heirs.” (Using translation from Ibn Mājah 2415)  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ إِذَا تُوُفِّيَ الْمُؤْمِنُ فِي عَهْدِ رَسُولِ اللهِ ﷺ وَعَلَيْهِ دَيْنٌ يَسْأَلُ «هَلْ تَرَكَ لِدَيْنِهِ مِنْ قَضَاءٍ» فَإِنْ قَالُوا نَعَمْ صَلَّى عَلَيْهِ وَإِنْ قَالُوا لَا قَالَ «صَلُّوا عَلَى صَاحِبِكُمْ» فَلَمَّا فَتَحَ اللهُ عَلَى رَسُولِهِ ﷺ الْفُتُوحَ قَالَ «أَنَا أَوْلَى بِالْمُؤْمِنِينَ مِنْ أَنْفُسِهِمْ فَمَنْ تُوُفِّيَ وَعَلَيْهِ دَيْنٌ فَعَلَيَّ قَضَاؤُهُ وَمَنْ تَرَكَ مَالًا فَهُوَ لِوَرَثَتِهِ»
