Surah Yunus, Verse 6

إِنَّ فِي ٱخۡتِلَٰفِ ٱلَّيۡلِ وَٱلنَّهَارِ وَمَا خَلَقَ ٱللَّهُ فِي ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِ لَأٓيَٰتٖ لِّقَوۡمٖ يَتَّقُونَ٦

inna fī ikh'tilāfi al-layli wal-nahāri wamā khalaqa l-lahu fī l-samāwāti wal-arḍi laāyātin liqawmin yattaqūna

Indeed, in the alternation of the night and the day and [in] what Allāh has created in the heavens and the earth are signs for a people who fear Allāh.
