سُورَةُ الفُرۡقَانِ
Surah Al-Furqaan·25:62
وَهُوَ الَّذِي جَعَلَ اللَّيْلَ وَالنَّهَارَ خِلْفَةً لِمَنْ أَرَادَ أَنْ يَذَّكَّرَ أَوْ أَرَادَ شُكُورًا٦٢
And He it is who causes the night and the day to succeed one another, [revealing Himself in His works] unto him who has the will to take thought - that is has the will to be grateful.
