Abu Dawud Book 14, Hadith Number 3194.
Chapter : Not known.
Narated By AbuHurayrah : Ali ibn Shammakh said: I was present with Marwan who asked AbuHurayrah: Did you hear how the Apostle of Allah (PBUH) used to pray over the dead? He said: Even with the words that you said. (The narrator said: They exchanged hot words between them before that.)
AbuHurayrah said: O Allah, Thou art its Lord. Thou didst create it, Thou didst guide it to Islam, Thou hast taken its spirit, and Thou knowest best its inner nature and outer aspect. We have come as intercessors, so forgive him.
