﴿ ٱلَّذِينَ قَالَ لَهُمُ ٱلنَّاسُ إِنَّ ٱلنَّاسَ قَدْ جَمَعُوا۟ لَكُمْ فَٱخْشَوْهُمْ فَزَادَهُمْ إِيمَٰنًۭا وَقَالُوا۟ حَسْبُنَا ٱللَّهُ وَنِعْمَ ٱلْوَكِيلُ ﴾

“those who have been warned by other people, "Behold, a host has gathered against you; so beware of them!" - whereupon this only increased their faith, so that they answered, "God is enough for us; and how excellent a guardian is He!””
