It is narrated from Awn bin Abdullah that he met an elder in the land of Sham and asked him: Did you hear anything directly from the Messenger of Allah (peace and blessings be upon him)? He replied: Yes, I heard him (peace and blessings be upon him) say: "Allahumma ighfir lana warhamna (O Allah, forgive us and have mercy on us)."
Imam Abu Ya'la recorded this hadith in his Musnad; in its chain, the narrator al-Mas'udi developed some weakness in memory, that is, ikhtilat (confusion), in the last part of his life; however, these blessed words of supplication are established and authenticated by other sahih hadith and supporting evidence.
