It is narrated from Hazrat Abu Umamah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Do not perform any prayer at the time of sunrise, because the sun rises between the two horns of Satan and at that time every disbeliever prostrates to it. Similarly, do not perform any prayer at the time of sunset, because the sun sets between the two horns of Satan and at that time every disbeliever prostrates to it. Likewise, do not perform any prayer at midday, because at that time Hell is kindled.
