Hadith 357
Sayyiduna Jabir (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) passed by a man who was standing on a rock performing prayer. Then the Prophet (peace and blessings be upon him) went to one side of Makkah (for some task) and stayed there for a little while. When he returned, he saw that man still in the same state, performing prayer. So the Prophet (peace and blessings be upon him) clasped his hands together and said: "O people! You must adopt moderation, you must adopt moderation. Indeed, Allah does not get tired, but you do get tired."
