Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him) the story of the man who was present in the mosque and was not performing the prayer correctly, and the Messenger of Allah (peace and blessings be upon him) taught him the prayer. In it there is also that he (peace and blessings be upon him) said: "Then prostrate with calmness."
