أَلَمْ تَرَ أَنَّ اللَّهَ يُولِجُ اللَّيْلَ فِي النَّهَارِ وَيُولِجُ النَّهَارَ فِي اللَّيْلِ وَسَخَّرَ الشَّمْسَ وَالْقَمَرَ كُلٌّ يَجْرِي إِلَى أَجَلٍ مُّسَمًّى وَأَنَّ اللَّهَ بِمَا تَعْمَلُونَ خَبِيرٌ
﴿٢٩﴾
سورة لقمان
(31/29) Did you not see that Allah causes the night to pass into the day and causes the day to pass into the night? (Allah) has subjected the sun and the moon (to His command). Each pursues its course (orbit) till an appointed term. Surely Allah is All-Informed of what you do.
Surah Luqman
