Some of the ones diving in their matter from the People of the Book will say: "They are three, their dog is the fourth," and another group will say: "They are five, their dog is the sixth," and the speech of the two groups is a word by suspicion from without a proof, and a third group says: "They are seven, and their dog is the eighth," say-O Messenger-: "My Lord He is more Knowing with their number, none knows their number except a few from His creation." So do not argue with the People of the Book in their number except a manifest argument no depth in it, by that you relate upon them what the revelation informed you by it only, and do not ask them about their number and their conditions; for indeed they do not know that.
