If the Qoran were the work of God, how could He swear by it?

The title has been chosen as something but the comments below it are totally unrelated. This is a strange way adopted by the writer!

The writer just makes a one line statement or rather a question on this matter. He asks why God swore on the Quran. The reason is that everything is Created by God and it is human nature to swear by things greater than himself. There is nothing greater than God and therefore, things on which God swears are different from what we swear by. The Quran is the word of God and He swears by His own word. What is the problem with that?

The writer has made the same point about marrying the ex-wife of the freed salve of the Prophet. He seems to have a problem with that. It has been answered where he first raised this concern.

The writer has again made the same statement about body parts giving testimony. His god is not All-Powerful and it is difficult for him to imagine an All-Powerful God who can do as He wills.
