What kind of example did the Messenger of Allah (peace be upon him) set when he (saw) said prayer standing?
 Anas b. Malik reported:                      The Messenger of Allah (may peace be upon him) fell down from a horse and his right side was grazed, and the rest of the hadith is the same with the addition of these words:" When he (the Imam) says prayer standing, you should also do so."
