And the Noble Prophet (peace and blessings be upon him) said: None of you will be saved by his deeds, but rather remain upright and close (to the right path). The noble 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 forgiveness and mercy.
