Surah Luqman (Luqman), Verse 29

اَلَمْ تَرَ اَنَّ اللّٰهَ یُوْلِجُ الَّیْلَ فِی النَّهَارِ وَیُوْلِجُ النَّهَارَ فِی الَّیْلِ وَسَخَّرَ الشَّمْسَ وَالْقَمَرَ كُلٌّ یَّجْرِیْۤ اِلٰۤی اَجَلٍ مُّسَمًّی وَّاَنَّ اللّٰهَ بِمَا تَعْمَلُوْنَ خَبِیْرٌ ۟

Alam tara annal laaha yoolijul laila fin nahaari wa yoolijun nahaara fil laili wa sakhkharash shamsa wal qamara kulluny yajreee ilaaa ajalim musammanw wa annal laaha bimaa ta'maloona Khabeer

“Seest thou not that Allah merges Night into Day and he merges Day into Night; that He has subjected the sun, and the moon (to his Law), each running its course for a term appointed; and that Allah is well-acquainted with all that ye do?”
