20:58
فَلَنَأْتِيَنَّكَ بِسِحْرٍ مِّثْلِهِۦ فَٱجْعَلْ بَيْنَنَا وَبَيْنَكَ مَوْعِدًا لَّا نُخْلِفُهُۥ نَحْنُ وَلَآ أَنتَ مَكَانًا سُوًى
falanatiyannaka bisiḥ'rin mith'lihi fa-ij'ʿal baynanā wabaynaka mawʿidan lā nukh'lifuhu naḥnu walā anta makānan suwan
We will confront you with sorcery to match your own: make an appointment between us which neither of us will fail to keep, in a mutually agreeable place.’
"Then verily, we can produce magic the like thereof; so appoint a meeting between us and you, which neither we nor you shall fail to keep, in an open place where both shall have a just and equal chance (and beholders could witness the competition)."
