And [if] they who are bent on denying the truth say [unto thee, O Prophet], "Thou hast not been sent [by God]", say thou: "None can bear witness between me and you as God does; and [none can bear witness as does] he who truly understands this divine writ.

The Unbelievers say: "No apostle art thou." Say: "Enough for a witness between me and you is God, and such as have knowledge of the Book."

They who disbelieve say: Thou art no messenger (of Allah). Say: Allah, and whosoever hath knowledge of the Scripture, is sufficient witness between me and you.

And those who disbelieve say: Thou art not a messenger. Say: Allah is sufficient for a witness between me and you and whoever has knowledge of the Book.

And those who have disbelieved say, "You are not a messenger." Say, [O Muhammad], "Sufficient is Allah as Witness between me and you, and [the witness of] whoever has knowledge of the Scripture."
