It is narrated from Hazrat Anas (may Allah be pleased with him) that one day the Prophet (peace and blessings be upon him) turned towards us after finishing the prayer and said, "By Him in Whose hand is the life of Muhammad (peace and blessings be upon him), if you had seen what I have seen, you would laugh little and weep much." The companions (may Allah be pleased with them) asked, "O Messenger of Allah (peace and blessings be upon him)! What have you seen?" He replied, "I have seen Paradise and Hell with my own eyes. And O people! I am your Imam, so do not go ahead of me in bowing, prostration, standing, sitting, or finishing (the prayer), for I see you from in front of me as well as from behind me."
