It is narrated from Hazrat Abu Saeed (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: No person will be able to enter Paradise without Allah’s mercy. 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 replied, "Not even me, unless my Lord covers me with His forgiveness and mercy." After saying this, the Prophet (peace and blessings of Allah be upon him) placed his hand on his head.
