Salamah - meaning, bin Al-Akwa' - said:"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."
أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، وَمُحَمَّدُ بْنُ الْمُثَنَّى، قَالاَ حَدَّثَنَا يَحْيَى، قَالَ حَدَّثَنَا يَزِيدُ بْنُ أَبِي عُبَيْدٍ، قَالَ حَدَّثَنَا سَلَمَةُ، - يَعْنِي ابْنَ الأَكْوَعِ - قَالَ أُتِيَ النَّبِيُّ صلى الله عليه وسلم بِجَنَازَةٍ فَقَالُوا يَا نَبِيَّ اللَّهِ صَلِّ عَلَيْهَا . قَالَ " هَلْ تَرَكَ عَلَيْهِ دَيْنًا " . قَالُوا نَعَمْ . قَالَ " هَلْ تَرَكَ مِنْ شَىْءٍ " . قَالُوا لاَ . قَالَ " صَلُّوا عَلَى صَاحِبِكُمْ " . قَالَ رَجُلٌ مِنَ الأَنْصَارِ يُقَالُ لَهُ أَبُو قَتَادَةَ صَلِّ عَلَيْهِ وَعَلَىَّ دَيْنُهُ . فَصَلَّى عَلَيْهِ .
