It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings of Allah be upon him) said: None of you will enter Paradise because of his deeds. The companions (may Allah be pleased with them) asked: O Messenger of Allah (peace and blessings of Allah be upon him), not even you? He said: Not even me, unless my Lord covers me with His forgiveness and mercy. And the Prophet (peace and blessings of Allah be upon him) placed his hand on his head.
