The Unbelievers say of those who believe: "If (this Message) were a good thing, (such men) would not have gone to it first, before us!" And seeing that they guide not themselves thereby, they will say, "this is an (old,) falsehood!"

And those who disbelieve (strong and wealthy) say of those who believe (weak and poor): "Had it (Islamic Monotheism to which Muhammad SAW is inviting mankind) been a good thing, they (weak and poor) would not have preceded us thereto!" And when they have not let themselves be guided by it (this Quran), they say: "This is an ancient lie!"

Those who disbelieve say to those who believe, “If it were anything good, they would not have preceded us to it.” And since they were not guided by it, they will say, “This is an ancient lie.”
