10:6
إِنَّ فِى ٱخْتِلَـٰفِ ٱلَّيْلِ وَٱلنَّهَارِ وَمَا خَلَقَ ٱللَّهُ فِى ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ لَـَٔايَـٰتٍ لِّقَوْمٍ يَتَّقُونَ
inna fī ikh'tilāfi al-layli wal-nahāri wamā khalaqa l-lahu fī l-samāwāti wal-arḍi laāyātin liqawmin yattaqūna
In the succession of night and day, and in what God created in the heavens and earth, there truly are signs for those who are aware of Him.
Verily, in the alternation of the night and the day and in all that Allâh has created in the heavens and the earth are Ayât (proofs, evidence, verses, lessons, signs, revelations, etc.) for those people who keep their duty to Allâh, and fear Him much.
