Sahih Muslim – The Times of the Prayer
Abdullah ibn ‘Amr reported that the Messenger of Allah, upon whom be peace, 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. It lasts until the time of the afternoon prayer. The time of the afternoon prayer is until the yellowing of the sun (during its setting). The time of the evening prayer is as long as twilight. The time of the night prayer is to the middle of a night of medium duration. And the time of the morning prayer is from the appearance of the dawn until the time of sunrise. When the sun rises, abstain from praying, as it rises between the horns of Satan.” (Related by Muslim. )
