صحيح مسلم

Abu Musa narrated on the authority of his father that a person came to the Messenger of Allah (ﷺ) for inquiring about the times of prayers. He (the Holy Prophet) gave him no reply (because he wanted to explain to him the times by practically observing these prayers). He then said the morning player when it was daybreak, but the people could hardly recognise one another. He then commanded and the Iqama for the noon prayer was pronounced when the tan had passed the meridian and one would say that it was midday but he (the Holy Prophet) knew batter than them. He then again commanded and the Iqama for the afternoon prayer was pronounced when the sun was high. He then commanded and Iqama for the evening prayer was pronounced when the sun had sunk. He then commanded and Iqama for the night prayer was pronounced when the twilight had disappeared. He then delayed the morning prayer on the next day (so much so) that after returning from it one would say that the sun had risen or it was about to rise. He then delayed the noon prayer till it was near the time of afternoon prayer (as it was observed yesterday). He then delayed the afternoon prayer till one after returning from it would say that the sun had become red. He then delayed the evening prayer till the twilight was about to disappear. He then delayed the night prayer till it was one-third of the night. He then called the inquirer in the morning and said: The time for prayers is between these two (extremes).
