القصص — Al-Qasas Ayat 73
وَمِنْ رَّحْمَتِهٖ جَعَلَ لَكُمُ الَّيْلَ وَالنَّهَارَ لِتَسْكُنُوْا فِيْهِ وَلِتَبْتَغُوْا مِنْ فَضْلِهٖ وَلَعَلَّكُمْ تَشْكُرُوْنَ
Wa mir raḥmatihī ja‘ala lakumul-laila wan-nahāra litaskunū fīhi wa litabtagū min faḍlihī wa la‘allakum tasykurūn(a).
"And out of His mercy He made for you the night and the day that you may rest therein and [by day] seek from His bounty and [that] perhaps you will be grateful."
