Majma al-Zawaid — Hadith 18434

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "On the Day of Resurrection three registers will be brought out for the son of Adam: one register containing righteous deeds, one register containing his sins, and one register mentioning the blessings of Allah Almighty upon him. Allah Almighty will say to His smallest blessing (the narrator says: I think the narration also has these words:) in the register of blessings (He will say to the smallest blessing in it): 'Take your price from his righteous deeds!' That blessing will take all of that person's righteous deeds; then it will step back and say: 'By Your might! I have not received my full due.' Then that person's sins and blessings will remain, since his righteous deeds will all have gone. When Allah Almighty intends to have mercy on a servant, He will say: 'O My servant! Allah Almighty has multiplied your good deeds and He has overlooked your sins (the narrator says: I think the narration also has these words:) and I have granted you My blessings as a gift.'"
Imam al-Bazzar recorded it; its chain contains Salih al-Murri, who is da'if (weak).
