فَاصۡبِرۡ اِنَّ وَعۡدَ اللّٰهِ حَقٌّ وَّلَا يَسۡتَخِفَّنَّكَ الَّذِيۡنَ لَا يُوۡقِنُوۡنَ
So be steadfast. Verily the Promise of Allah is true. Let not those who lack certitude of faith enfeeble you (on account of the grief over their straying and discomfort for their guidance. O life of the universe, let not their disbelief become a grief consuming your soul).
