salaam aleykom, I am not a big fan of these sort of miracles because they are not convincing and anyone can make such claims. This is how that fake Islamic cult by rashad khalifah was invented. that kafir claimed to have found a mathematical 'miracle' in the Quran and became famous by it even though it is a fraud. but what makes it better for his cult members is that many Muslims fell for it and even scholars praised him and later rejected him for claiming to be a messenger and making all kinds of silly claims. Had Muslims been more careful early on, this cult would not even exist today but they are alive and posing as Muslims. The Quran is a living miracle and this sort of stuff is no match compared to it.
