﴿ فَإِنِ ٱسْتَكْبَرُوا۟ فَٱلَّذِينَ عِندَ رَبِّكَ يُسَبِّحُونَ لَهُۥ بِٱلَّيْلِ وَٱلنَّهَارِ وَهُمْ لَا يَسْـَٔمُونَ ۩ ﴾
“And though some be too proud [to listen to this call], they who [in their hearts] are with thy Sustainer extol His limitless glory by night and by day, and never grow weary [thereof].”
