"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."
Sunan an-Nasa'i Book 21, Hadith 144
← Previous Hadith 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

Sunan an-Nasa'i Book 21, Hadith 143 Next Hadith → "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."
