It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: None of you will be saved by his deeds. The companions (may Allah be pleased with them) asked, "O Messenger of Allah! Not even you?" He replied: Not even me, unless my Lord covers me with His forgiveness and mercy. He (peace and blessings be upon him) repeated this sentence two or three times.
