كَذَٰلِكَ يَطۡبَعُ ٱللَّهُ عَلَىٰ قُلُوبِ ٱلَّذِينَ لَا يَعۡلَمُونَ
Thus doth Allah seal the hearts of those who know not.
فَٱصۡبِرۡ إِنَّ وَعۡدَ ٱللَّهِ حَقّٞۖ وَلَا يَسۡتَخِفَّنَّكَ ٱلَّذِينَ لَا يُوقِنُونَ
So have patience (O Muhammad)! Allah's promise is the very truth, and let not those who have no certainty make thee impatient.
