Quran 28:73 from Surah Al-Qasas on Divine Marvels.
وَمِن رَّحۡمَتِهِۦ جَعَلَ لَكُمُ ٱلَّيۡلَ وَٱلنَّهَارَ لِتَسۡكُنُواْ فِيهِ وَلِتَبۡتَغُواْ مِن فَضۡلِهِۦ وَلَعَلَّكُمۡ تَشۡكُرُونَ
English translation: And from His Mercy He made for you the night and the day that you may rest therein and that you may seek from His Bounty and so that you may be grateful
Transliteration: wamin rahmatihi ja'ala lakumu al-layla wal-nahara litaskunu fihi walitabtaghu min fadlihi wala'allakum tashkuruna
