• Day in the Qur’an is not just sunlight, but rather an independent cosmic sign governed by direct divine management. • The Qur’an differentiates between the role of the sun as a source of energy and day as a cosmic phenomenon, as the sun is a lamp and day is radiance. • The Qur’an confirms that God is able to create day without the sun, as in the afterlife where the cosmic order changes. • Modern science confirms that day results from the reflection of the sun’s rays on the atmosphere, and this does not contradict the Qur’an. • Day in the Qur’an is evidence that the universe is governed by divine will and does not depend on material causes alone. • Day is a sign that reminds man that God is able to create light without the sun, as in Paradise. • Day is a divine signature on the greatness of the Creator who subjected the universe to His will.
