فَلَنَأْتِيَنَّكَ بِسِحْرٍ مِّثْلِهِ فَاجْعَلْ بَيْنَنَا وَبَيْنَكَ مَوْعِدًا لَّا نُخْلِفُهُ نَحْنُ وَلَا أَنتَ مَكَانًا سُوًى
[20:58]
So we too will produce before you magic like it, therefore make between us and you an appointment, which we should not break, (neither) we nor you, (in) a central place.
"But we can surely produce magic to match thine! So make a tryst between us and thee, which we shall not fail to keep - neither we nor thou - in a place where both shall have even chances."
But we surely can produce for thee magic the like thereof; so appoint a tryst between us and you, which neither we nor thou shall fail to keep, at a place convenient (to us both).
