﴿ قَالُوا۟ يَٰمُوسَىٰٓ إِنَّا لَن نَّدْخُلَهَآ أَبَدًۭا مَّا دَامُوا۟ فِيهَا ۖ فَٱذْهَبْ أَنتَ وَرَبُّكَ فَقَٰتِلَآ إِنَّا هَٰهُنَا قَٰعِدُونَ ﴾

“[But] they said: "O Moses! Behold, never shall we enter that [land] so long as those others are in it. Go forth, then, thou and thy Sustainer, and fight, both of you! We, behold, shall remain here!"”
