Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that one day the Messenger of Allah (peace and blessings be upon him) finished the prayer and turned his blessed face towards us and said: "O people, I am your imam, so do not precede me in bowing (ruku‘) and prostration (sujud). Do not precede me in standing, sitting, or finishing the prayer. Indeed, I see you from behind me, and by the One in Whose hand is my soul, if you were to see what I see, you would laugh little and weep much." Sayyiduna Anas (may Allah be pleased with him) says that we asked, "O Messenger of Allah (peace and blessings be upon him), what have you seen?" He (peace and blessings be upon him) replied: "I have seen Paradise and Hell."
