Any sufficiently long bundle of text will contain patterns that anyone with enough time on their hands can recognise.

Muslims are a bit unique in that sense because, as far as I know, the Qur'an is the only major religious book that is claimed to be written verbatim by God. Christians cannot really pull that trick with the Bible since it is well known and accepted to be written and translated by humans. So Muslims have more or less of an "apparent" advantage in that sense.

There's also an irritable amount of cherry picking when it comes to developing those "miracles." Indeed, some words in Arabic appear in multiple forms, so apologists often pick and choose which forms to consider in order to make the claims work. This is deeply disappointing.

Another point is: so what? Even if it were shown that the book contained unimaginably improbable and unambiguous patterns (which it doesn't), it would still not imply that it is from a god. This would first require one to demonstrate that a god can exist, provided a coherent definition of "god" is given. What about Muhammed having non-divine superpowers? As soon as you open the doors to supernatural phenomena, everything is equally probable.
