ٱلَّذِينَ قَالَ لَهُمُ ٱلنَّاسُ إِنَّ ٱلنَّاسَ قَدْ جَمَعُوا۟ لَكُمْ فَٱخْشَوْهُمْ فَزَادَهُمْ إِيمَٰنًۭا وَقَالُوا۟ حَسْبُنَا ٱللَّهُ وَنِعْمَ ٱلْوَكِيلُ
Those unto whom men said: Lo! the people have gathered against you, therefor fear them. (The threat of danger) but increased the faith of them and they cried: Allah is Sufficient for us! Most Excellent is He in Whom we trust!
