Sahih Muslim 1388

Abdullah b. 'Amr reported:The Messenger of Allah (ﷺ) said: The time of the noon prayer is when the sun passes the meridian and a man's shadow is the same (length) as his height, (and it lasts) as long as the time for the afternoon prayer has not come; the time for the afternoon prayer is as long as the sun has not become pale; the time of the evening prayer is as long as the twilight has not ended; the time of the night prayer is up to the middle of the average night and the time of the morning prayer is from the appearance of dawn, as long as the sun has not risen; but when the sun rises, refrain from prayer for it rises between the horns of the devil
