And yet, they [who are bent on denying the truth] assert, "[Muhammad] has invented it!" Say [unto them]: "Produce, then, a surah of similar merit; and [to this end] call to your aid whomever you can, other than God, if what you say is true !

Or do they say, "He forged it"? say: "Bring then a Sura like unto it, and call (to your aid) anyone you can besides God, if it be ye speak the truth!"

Or say they: He hath invented it? Say: Then bring a surah like unto it, and call (for help) on all ye can besides Allah, if ye are truthful.

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

Or do they say [about the Prophet], "He invented it?" Say, "Then bring forth a surah like it and call upon [for assistance] whomever you can besides Allah , if you should be truthful."
