Salamah ibn al-Akwa’ reported: The Prophet, peace and blessings be upon him, was presented with a funeral for him to pray over it. The Prophet said, “Does he have debt?” They said no, so the Prophet prayed over him. Then he was presented with another funeral and the Prophet said, “Does he have debt?” They said yes. The Prophet said, “Pray over your companion.” Abu Qatadah said, “I take responsibility for his debt, O Messenger of Allah,” so the Prophet prayed over him.

عَنْ سَلَمَةَ بْنِ الْأَكْوَعِ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أُتِيَ بِجَنَازَةٍ لِيُصَلِّيَ عَلَيْهَا فَقَالَ هَلْ عَلَيْهِ مِنْ دَيْنٍ قَالُوا لَا فَصَلَّى عَلَيْهِ ثُمَّ أُتِيَ بِجَنَازَةٍ أُخْرَى فَقَالَ هَلْ عَلَيْهِ مِنْ دَيْنٍ قَالُوا نَعَمْ قَالَ صَلُّوا عَلَى صَاحِبِكُمْ قَالَ أَبُو قَتَادَةَ عَلَيَّ دَيْنُهُ يَا رَسُولَ اللَّهِ فَصَلَّى عَلَيْهِ
2173 صحيح البخاري كتاب الكفالة باب من تكفل عن ميت دينا فليس له أن يرجع
قَالَ ابْنُ بَطَّالٍ ذَهَبَ الْجُمْهُورُ إِلَى صِحَّةِ هَذِهِ الْكَفَالَةِ وَلَا رُجُوعَ لَهُ فِي مَالِ الْمَيِّتِ
