Musannaf Ibn Abi Shaybah

Hazrat Usman bin Shamas narrates that we were with Hazrat Abu Hurairah when Marwan passed by him. He said to him: "Narrate to us a hadith of the Messenger of Allah, peace and blessings be upon him." Then he went away, and after a short while he returned. So we said: "Now he will sit with him." Then he said: "Did you hear the Messenger of Allah, peace and blessings be upon him, recite any supplication over the funeral prayer?" He replied: "I heard him supplicate thus: 'You alone guided him to Islam, and You alone took his soul. You know his hidden and open matters. We have come to You as intercessors for him, so forgive him.'"
