And this Quran is not such as could be forged by those besides Allah, but it is a verification of that which is before it and a clear explanation of the book, there is no doubt in it, from the Lord of the worlds.

Or do they say: He has forged it? Say: Then bring a chapter like this and invite whom you can besides Allah, if you are truthful.

Or, do they say: He has forged it. Say: Then bring ten forged chapters like it and call upon whom you can besides Allah, if you are truthful.
