الاسراۤء — Al-Isra' Ayat 12
وَجَعَلْنَا الَّيْلَ وَالنَّهَارَ اٰيَتَيْنِ فَمَحَوْنَآ اٰيَةَ الَّيْلِ وَجَعَلْنَآ اٰيَةَ النَّهَارِ مُبْصِرَةً لِّتَبْتَغُوْا فَضْلًا مِّنْ رَّبِّكُمْ وَلِتَعْلَمُوْا عَدَدَ السِّنِيْنَ وَالْحِسَابَۗ وَكُلَّ شَيْءٍ فَصَّلْنٰهُ تَفْصِيْلًا
Wa ja‘alnal-laila wan-nahāra āyataini fa maḥaunā āyatal-laili wa ja‘alnā āyatan-nahāri mubṣiratal litabtagū faḍlam mir rabbikum wa lita‘lamū ‘adadas-sinīna wal-ḥisāb(a), wa kulla syai'in faṣṣalnāhu tafṣīlā(n).
"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."
