Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: The time for Zuhr prayer is from the declining of the sun until a man's shadow is equal to his height, that is, until the time for Asr begins. The time for Asr prayer is until the sun becomes yellow. The time for Maghrib prayer is until the twilight disappears. The time for Isha prayer is until the first half of the night. The time for Fajr prayer is from the appearance of dawn until sunrise. When the sun begins to rise, refrain from prayer, because it rises between the two horns of Satan.
