Fussilat - 41:38

فَإِنِ اسْتَكْبَرُوا فَالَّذِينَ عِندَ رَبِّكَ يُسَبِّحُونَ لَهُ بِاللَّيْلِ وَالنَّهَارِ وَهُمْ لَا يَسْأَمُونَ
[41:38]
But if they are proud, yet those with your Lord glorify Him during the night and the day, and they are not tired.
But is the (Unbelievers) are arrogant, (no matter): for in the presence of thy Lord are those who celebrate His praises by night and by day. And they never flag (nor feel themselves above it).
But if they are too proud - still those who are with thy Lord glorify Him night and day, and tire not.
