Have you not seen that Allah takes from the hours of the night, so the day lengthens, and the night shortens, and takes from the hours of the day, so the night lengthens, and the day shortens, and subjected for you the sun and the moon, each of them both flowing in its orbit to a known specified term, and that Allah is Aware upon all the deeds of the creation of good or evil, nothing of it is hidden from Him?
