What did the Prophet Muhammad (saw) instruct us to do when he said prayer in an erect posture?
 Anas reported:                      The Messenger of Allah (may peace be upon him) rode a horse and fell down from it and his right side was grazed, and the rest of the hadith is the same, and (these words) are found in it:" When he (the Imam) says prayer in an erect posture, you should also say it in an erect posture."
