Translation of the verse 58 from Surah Ta-Ha : Number of verses 135 - - page 315 - Part 16.
"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 wide place where both shall have a just and equal chance (and beholders could witness the competition)."
Then we will surely bring you magic like it, so make between us and you an appointment, which we will not fail to keep and neither will you, in a place assigned."
(20:58) Well, we will also bring as strong a sorcery as yours. So settle with us when and where should the encounter take place; then neither should we back out of this agreement nor you. Come out in the open field."
