Sayyiduna Buraydah (may Allah be pleased with him) relates: We were with the Prophet (peace and blessings be upon him) until we reached the place called "Waddan" (the narrator is unsure; perhaps the words are:) reached some graves. Then the Prophet (peace and blessings be upon him) supplicated for intercession for his mother (the narrator relates: I think the narration also contains these words:) and Sayyiduna Jibril (peace be upon him) struck the chest of the Prophet (peace and blessings be upon him) and said: "Do not seek forgiveness for one who died as an idolater."
Al-Bazzar recorded it and said: No one narrated it with this chain except Muhammad bin Jabir from Simak bin Harb. (Allamah al-Haythami says:) I say: I have not seen anyone who mentions this narrator, Muhammad bin Jabir.
