Sura 3 Ali 'Imran (Family of Imran), ayah 190

1. إِنَّ فِي خَلْقِ السَّمَاوَاتِ وَالْأَرْضِ وَاخْتِلَافِ اللَّيْلِ وَالنَّهَارِ لَآيَاتٍ لِأُولِي الْأَلْبَابِ

   Indeed, in the creation of the heavens and the earth and the alternation of the night and the day are signs for those of understanding.
