It is narrated from Hazrat Rifa’ah (may Allah be pleased with him) that once the Noble Prophet (peace and blessings be upon him) was sitting in the mosque when a man came and began to pray near the Noble Prophet (peace and blessings be upon him). After finishing the prayer, he came to the service of the Noble Prophet (peace and blessings be upon him), so the Noble Prophet (peace and blessings be upon him) said to him, "Repeat your prayer, for you have not prayed properly." He went away and prayed again as he had done before, then returned. The Noble Prophet (peace and blessings be upon him) again said to him, "Repeat your prayer, for you have not prayed properly." He said, "O Messenger of Allah (peace and blessings be upon him), teach me how to pray." The Noble Prophet (peace and blessings be upon him) said, "When you face the Qiblah, say Allahu Akbar, then recite Surah Al-Fatihah and with it whatever Surah you wish. When you bow (ruku’), place your palms on your knees, straighten your back, and make your ruku’ well-balanced. When you raise your head from ruku’, straighten your back until all the bones return to their joints. And when you prostrate (sajdah), do it well, and stand up straight. If you complete your prayer in this manner, you have performed it perfectly, and if you are negligent in any of these things, your prayer is incomplete."
