Al Isra, 12 Ayah
17:12
وَجَعَلۡنَا ٱلَّيۡلَ وَٱلنَّهَارَ ءَايَتَيۡنِۖ فَمَحَوۡنَآ ءَايَةَ ٱلَّيۡلِ وَجَعَلۡنَآ ءَايَةَ ٱلنَّهَارِ مُبۡصِرَةٗ لِّتَبۡتَغُواْ فَضۡلٗا مِّن رَّبِّكُمۡ وَلِتَعۡلَمُواْ عَدَدَ ٱلسِّنِينَ وَٱلۡحِسَابَۚ وَكُلَّ شَيۡءٖ فَصَّلۡنَٰهُ تَفۡصِيلٗا ١٢
Wa Ja`alnā Al-Layla Wa An-Nahāra 'Āyatayni ۖ Famaĥawnā 'Āyata Al-Layli Wa Ja`alnā 'Āyata An-Nahāri Mubşiratan Litabtaghū Fađlāan Min Rabbikum Wa Lita`lamū `Adada As-Sinīna Wa Al-Ĥisāba ۚ Wa Kulla Shay'in Faşşalnāhu Tafşīlāan
And We have made the night and day two signs, and We erased the sign of the night and made the sign of the day visible that you may seek bounty from your Lord and may know the number of years and the account [of time]. And everything We have set out in detail.
