On the following day he prayed the noon prayer with me when his shadow was as long as himself; he prayed the afternoon prayer with me when his shadow was twice as long as himself; he prayed the sunset prayer at the time when one who is fasting breaks the fast; he prayed the night prayer with me when about the third of the night had passed; and he prayed the dawn prayer with me when there was a fair amount of light.
Then turning to me he said: Muhammad, this is the time observed by the prophets before you, and the time is anywhere between two times.
