Quran 17:12 from Surah Al-Israa on Divine Marvels.
وَجَعَلۡنَا ٱلَّيۡلَ وَٱلنَّهَارَ ءَايَتَيۡنِۖ فَمَحَوۡنَآ ءَايَةَ ٱلَّيۡلِ وَجَعَلۡنَآ ءَايَةَ ٱلنَّهَارِ مُبۡصِرَةٗ لِّتَبۡتَغُواْ فَضۡلٗا مِّن رَّبِّكُمۡ وَلِتَعۡلَمُواْ عَدَدَ ٱلسِّنِينَ وَٱلۡحِسَابَۚ وَكُلَّ شَيۡءٖ فَصَّلۡنَٰهُ تَفۡصِيلٗا
English translation: And We have made the night and the day (as) two signs Then We erased (the) sign (of) the night and We made (the) sign (of) the day visible that you may seek bounty from your Lord and that you may know (the) number (of) the years and the account And every thing We have explained it (in) detail
