Surah Al-Qasas (The Stories), Verse 73

وَمِنْ رَّحْمَتِهٖ جَعَلَ لَكُمُ الَّیْلَ وَالنَّهَارَ لِتَسْكُنُوْا فِیْهِ وَلِتَبْتَغُوْا مِنْ فَضْلِهٖ وَلَعَلَّكُمْ تَشْكُرُوْنَ ۟

Wa mir rahmatihee ja'ala lakumul laila wannahaara litaskunoo feehi wa litabtaghoo min fadlihee wa la'allakum tashkuroon

“It is out of His Mercy that He has made for you Night and Day,- that ye may rest therein, and that ye may seek of his Grace;- and in order that ye may be grateful.”
