Sahih al-Bukhari 2295
Narrated Salama bin Al-Akwa`:
A dead person was brought to the Prophet (ﷺ) so that he might lead the funeral prayer for him. He asked, 
"Is he in debt?" When the people replied in the negative, he led the funeral prayer. Another dead 
person was brought and he asked, "Is he in debt?" They said, "Yes." He (refused to lead the prayer 
and) said, "Lead the prayer of your friend." Abu Qatada said, "O Allah's Messenger (ﷺ)! I undertake to pay 
his debt." Allah's Messenger (ﷺ) then led his funeral prayer.
حَدَّثَنَا أَبُو عَاصِمٍ، عَنْ يَزِيدَ بْنِ أَبِي عُبَيْدٍ، عَنْ سَلَمَةَ بْنِ الأَكْوَعِ ـ رضى الله عنه ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم أُتِيَ بِجَنَازَةٍ، لِيُصَلِّيَ عَلَيْهَا، فَقَالَ ‏"‏ هَلْ عَلَيْهِ مِنْ دَيْنٍ ‏"‏‏.‏ قَالُوا لاَ‏.‏ فَصَلَّى عَلَيْهِ، ثُمَّ أُتِيَ بِجَنَازَةٍ أُخْرَى، فَقَالَ ‏"‏ هَلْ عَلَيْهِ مَنْ دَيْنٍ ‏"‏‏.‏ قَالُوا نَعَمْ‏.‏ قَالَ ‏"‏ صَلُّوا عَلَى صَاحِبِكُمْ ‏"‏‏.‏ قَالَ أَبُو قَتَادَةَ عَلَىَّ دَيْنُهُ يَا رَسُولَ اللَّهِ‏.‏ فَصَلَّى عَلَيْهِ‏.‏
