Sorry, I wasn't upset, I just have a very blunt way of writing, and it often comes across that way.
The problem is you're still moving the goalposts. You have gone from "If you can find a single contradiction in the Qur'an I'm happy to accept that the Qur'an must be the work of man and not God." to "You provided too many contradictions, so I will not accept the method with which you provided them." to "Pick one, and I will prove it does not say what it says it does, and by extension, that all of them are actually not contradictions." You also threw in a little 'if it's a contradiction in English, then that's a human error, as it's not a contradiction in Arabic', which totally ignores that you're then saying that human error can come into play when you're at the same time claiming it can't.
That said, I DO have one that I particularly like, but I'm not willing to play the 'moving the goalposts until I win' game.
Also, if you want to convince the non-religious, you need to use logic. And one thing you need to be aware of is that a conclusion cannot use itself as a reference. What I mean is that you cannot say that the Qu'ran is the truth because Allah created the Qu'ran (which itself comes from the Qu'ran). That is a logical fallacy called a circular reference. Would you accept the same (very common) argument from a Christian, that the Bible is the Truth because it's the Word of God, as explained by the Bible? No, you wouldn't.
To convince the non-believer, you need to convince them logically. That means evidence of creation claims. Evidence of visitation by angels. And yes, that means proving the logical superiority of the ethical system espoused.
