In the name of Allah, Most Gracious, Most Merciful.
17:12
وَجَعَلْنَا ٱلَّيْلَ وَٱلنَّهَارَ ءَايَتَيْنِ ۖ فَمَحَوْنَآ ءَايَةَ ٱلَّيْلِ وَجَعَلْنَآ ءَايَةَ ٱلنَّهَارِ مُبْصِرَةً لِّتَبْتَغُوا۟ فَضْلًا مِّن رَّبِّكُمْ وَلِتَعْلَمُوا۟ عَدَدَ ٱلسِّنِينَ وَٱلْحِسَابَ ۚ وَكُلَّ شَىْءٍ فَصَّلْنَـٰهُ تَفْصِيلًا
17:12
And We have appointed the night and the day as two Ayat (signs). Then, We have obliterated the sign of the night (with darkness) while We have made the sign of the day illuminating, that you may seek bounty from your Lord, and that you may know the number of the years and to count (periods of time). And We have explained everything (in detail) with full explanation. - Safi-ur-Rahman al-Mubarakpuri (English)
