Abu Hazim said: I heard Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) say: I saw the Messenger of Allah (peace and blessings be upon him) stand on his pulpit and lead the people in prayer while standing on the pulpit. He (peace and blessings be upon him) said the takbir on the pulpit, then bowed, then stepped back and prostrated at the foot of the pulpit, then went back up, and continued doing likewise until he completed his prayer. Then he turned to the people and said: "O people, I did this only so that you may follow me and learn my prayer."
