Musnad Ahmad 30:1409

'Affan narrated to us, Khalid ibn 'Abdullah narrated to us, from Suhayl, from his father, from Abu Hurayrah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "There is not one among you whom his deeds will save." They said: "Not even you, O Messenger of Allah?" He said: "Not even me, unless Allah covers me with mercy from Him."
