Mishkat al-Masabih #2799

Abu Sa'id al-Khudrl said that a corpse was brought to the Prophet on a bier for him to pray over it and he asked the people whether their friend owed anything. On being told that he did, he asked whether he had left anything to discharge it, and when they replied that he had not, he told them to pray over him. But ‘Ali b. Abu Talib said, “I shall be responsible for his debt, Messenger of God,” so he went forward and prayed over him. A version has something to the same effect, adding that he said, “May God redeem your pledges from hell as you have redeemed the pledges of your brother Muslim! No Muslim will discharge his brother’s debt without God redeeming his pledges on the day of resurrection.” It is transmitted in Sharh as- sunna.
