Al-Furqan 62

وَهُوَ ٱلَّذِى جَعَلَ ٱلَّيْلَ وَٱلنَّهَارَ خِلْفَةً لِّمَنْ أَرَادَ أَن يَذَّكَّرَ أَوْ أَرَادَ شُكُورًا

wahuwa alladhī jaʿala al-layla wal-nahāra khil'fatan liman arāda an yadhakkara aw arāda shukūran

And it is He who has made the night and the day in succession for whoever desires to remember or desires gratitude.
