﴿ فَلَنَأْتِيَنَّكَ بِسِحْرٍۢ مِّثْلِهِۦ فَٱجْعَلْ بَيْنَنَا وَبَيْنَكَ مَوْعِدًۭا لَّا نُخْلِفُهُۥ نَحْنُ وَلَآ أَنتَ مَكَانًۭا سُوًۭى ﴾

“In that case, we shall most certainly produce before thee the like thereof! Appoint, then, a tryst between us and thee - which we shall not fail to keep, nor [mayest] thou -at a suitable place!"”

But we surely can produce magic the like thereof) like the magic you produced; (so appoint a tryst) appoint a time of encounter (between us and you, which neither we nor thou shall fail to keep, at a place convenient (to us both)) other than this place; it is also said that this means: a place that is fair to both of us.
