﴿ أَلَمْ تَرَ أَنَّ ٱللَّهَ يُولِجُ ٱلَّيْلَ فِى ٱلنَّهَارِ وَيُولِجُ ٱلنَّهَارَ فِى ٱلَّيْلِ وَسَخَّرَ ٱلشَّمْسَ وَٱلْقَمَرَ كُلٌّۭ يَجْرِىٓ إِلَىٰٓ أَجَلٍۢ مُّسَمًّۭى وَأَنَّ ٱللَّهَ بِمَا تَعْمَلُونَ خَبِيرٌۭ ﴾

“Art thou not aware that it is God who makes the night grow longer by shortening the day, and makes the day grow longer by shortening the night, and that He has made the sun and the moon subservient [to His laws], each running its course for a term set [by Him] and that God is fully aware of all that you do?”

(Hast thou not seen) have you not been informed in the Qur'an (how Allah causeth the night to pass into the day) He makes the night longer than the day such that, for example, the night is 15 hours while the day is only nine hours (and causeth the day to pass into the night) He makes the day longer than the night such that, for example, the day consists of 15 hours while the night only of nine hours, (and hath subdued) made subservient (the sun and the moon, each running unto an appointed term) to an appointed time in well know trajectories; (and that Allah is Informed of what ye do) of good or evil?
