Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that one day, after finishing the prayer, the Messenger of Allah (peace and blessings be upon him) turned towards us and said: O people! Indeed, I am your Imam, so do not go ahead of me in bowing, prostration, standing, sitting, or in saying the salam. I see you from in front of me and from behind me. By the One in Whose hand is my soul! If you were to see what I have seen, you would laugh little and weep much. They said: O Messenger of Allah! What have you seen? The Prophet (peace and blessings be upon him) replied: I have seen Paradise and Hell. In another narration, it is mentioned: And the Prophet (peace and blessings be upon him) encouraged them to perform prayer.
