CIRA International find Quranic irony; 12:111 confirms Biblical Joseph?

In answer to the video "Yusuf 12:111 - The Quran Affirms the Bible"

The verse 12:111 comes in the context of demonstrating that the prophet Muhammad fits in the pattern of prophethood. Here is a man who 

1) comes from a common background of his addressees, meaning they know him very well, yet claims to be a Messenger, in fact the Final Messenger of God
2) warns his people of Divine chastisement
3) the chastisement comes home to roost and the partisans of the Prophet are established in the land

This is the exact process that occurred with the Bani Israil in the time of Moses, with the drowning of the host of Pharaoh and the deliverance of the Israelites, with the uprooting of the Canaanites and the establishement of the way of God. Not to mention, the Quranic invitation to the Arabs to see or recall for themselves the fate of the deniers of Nuh, Lut, Saleh, Shuayb, Hud... It is a Book of Warning that has already delivered its judgment in this world

53:36"This is a warner of the warners of old"  

54:42-5"Are the unbelievers of yours better than these, or is there an exemption for you in the scriptures?...Soon shall the hosts be routed, and they shall turn (their) backs"  

12:111"There is a lesson in these stories of the former people for those posessing common sense. It is not a narrative which could be forged, but a verification of what was before it".

As said in Deuteronomy regarding the awaited prophet

"If any man will not listen to my words which he speaks in my name, I myself will make him answer for it".
