Those who disbelieve say of the believers, ‘If there were any good in this Quran, they would not have believed in it before we did,’and, since they refuse to be guided by it, they say, ‘This is an ancient fabrication.’
Those who deny say of those who believe, "If it were any good, they would not have reached it before us." And since they refuse to be guided by it, they will say, "This is an ancient lie."
