The Islamic day begins after sunset and ends before sunset of the next day. The ‘day’ or ‘date’ being determined by sunset does not affect the determination of the morning or evening. The word ‘day’ simply means a time span of 24 hours and does not connote light in the sky, as opposed to darkness.

Ibn al-Qayyim quoted the verse, “and glorify the Praises of your Lord, before the rising of the sun and before (its) setting’[Qaaf 50:39]and explained that it means before the sun rises and before it sets. The time for that is between dawn and sunrise, and between ‘Asr and Maghrib. [al-Waabil al-Sayyib, 200]
