Surat Luqman (Luqman) - لقمان

أَلَمْ تَرَ أَنَّ ٱللَّهَ يُولِجُ ٱلَّيْلَ فِى ٱلنَّهَارِ وَيُولِجُ ٱلنَّهَارَ فِى ٱلَّيْلِ وَسَخَّرَ ٱلشَّمْسَ وَٱلْقَمَرَ كُلٌّ يَجْرِىٓ إِلَىٰٓ أَجَلٍ مُّسَمًّى وَأَنَّ ٱللَّهَ بِمَا تَعْمَلُونَ خَبِيرٌ ﴿٢٩﴾

Do you not see that Allah makes the night to enter into the day, and He makes the day to enter into the night, and He has made the sun and the moon subservient (to you); each pursues its course till an appointed time; and that Allah is Aware of what you do?
