فصّلت — Fussilat Ayat 38
فَاِنِ اسْتَكْبَرُوْا فَالَّذِيْنَ عِنْدَ رَبِّكَ يُسَبِّحُوْنَ لَهٗ بِالَّيْلِ وَالنَّهَارِ وَهُمْ لَا يَسْـَٔمُوْنَ ۩
Fa inistakbarū fal-lażīna ‘inda rabbika yusabbiḥūna lahū bil-laili wan-nahāri wa hum lā yas'amūn(a).
"But if they are arrogant - then those who are near your Lord exalt Him by night and by day, and they do not become weary."
