As'salamu Alaikum dear brother Farhan,
Thank you dear brother. Ramadan Mubarak for you and your family, and to also to all of the Muslims who are reading this and to their families. Ameen.
The image the you provided akhi seems to be a non-Arabic Quran akhi. Yes, the letters are all in Arabic, but I don't know which Quran is this. It is certainly not the official Quran that we have, which I provided an image of the Noble Verse above. And like I said, I checked the Abdullah Yusuf Ali Quran, and I found the spelling to be exactly as the one I provided above, which you also correctly provided in the text above. But as to this image I am not sure if it's even an official Arabic Noble Quran. It could be from another country. Or it could be a copy of a Quran that is altered to help the reader read the Holy Quran with Tajweed. I am not sure. But for sure, this is not the way the Noble Verse is spelled. The same goes with all of the Noble Verses in the gif image.
As to whether these rules existed 1,400 years ago or not, here is what is Miraculous about the Noble Quran:
1- The Holy Quran that we have today is the official copy that Allah Almighty Sent down to Prophet Muhammad, peace be upon him.
2- The way the Holy Book is officially written is the way Allah Almighty officially wanted it to be.
This is further proven here:

I personally believe that the Holy Quran created these rules. In other words, they came to existence from the Holy Quran's Writing. Again, this is due to the Miracle of the Holy Quran's Text. Please visit the link that I gave for more details.
I hope this helps insha'Allah. Please feel free to ask more questions dear brother.
Take care,
Osama Abdallah
