It is narrated from Ibn A'idh (may Allah have mercy on him) that the Messenger of Allah (peace and blessings be upon him) went out for the funeral of a man from the Ansar. Then he narrated the whole hadith, in which there are also these (words): the Messenger of Allah (peace and blessings be upon him) said: "O Umar, you will certainly not be questioned about the (general) deeds of people, but you will all be questioned (particularly) about the prayer."
Imam Ahmad bin Mani' narrated this hadith in his Musnad. All the narrators of its chain are thiqat (trustworthy); however, Ibn A'idh is a Successor (Tabi'i), so this narration is mursal.
