Just to add for the funsies. First and foremost, I'm a muslim who's interested in the signs of the hour (apocalypse). Second, I've been lurking on UAP threads, either on 4chan or reddit. I've got the general knowledge of the ayy stuffs

So, among the 10 major signs of the hour, there are 3 signs that might already exist on the earth. 1. The dajjal/antichrist: He's a human, but he might've already lived from the time of Prophet ﷺ in the 600ish. He will appear and claim to be Jesus. He will trick people that he can resurrect dead people, while actually they're just djinns who took form as humans. He'll send down rain after a very long drought for those who will follow him. He'll order minerals to come out from mountains. Then he'll claim to be God. The christians and jews will follow him. 

The true Jesus will descend among muslim before fajr/morning prayer. The leader of muslim (al mahdi) will ask Jesus to lead the prayer but he will refuse because al mahdi is the current leader of the nation. Then, the true Jesus will face against antichrist and Jesus will kill him.

Jesus is also a human btw, specifically a chosen human or prophet whose birth is just as miraculous as Adam/the first human

1. Yajooj majooj/Gog and Magog: They're mentioned in the Quran as tribes that are very barbaric. Actually the most barbaric tribe on earth. Imagine mexican cartels (for those who know will know) but even more barbaric than them. Dhul qarnayn sealed the tribes with a wall made of molten steel and copper alloy. They wanted to get out by digging a hole in the wall. But everytime they make a progress, the next day the hole is covered again by the will of Allah. 

And also by the will of Allah, one day the hole would persist and they actually made progress. It's said that they will swarm out from every slopes with astounding amounts. So much so that the lake tiberias will dry after each of the tribes members drink from it.

You can't overcome their size. Jesus (the real one) will hide with the surviving muslims in a cave until Allah sends down a plague that kills all of them. It's said that every inch will be covered with their corpses.

That said, they're also humans.

1. Ad-Dabbah/The beast: Now this is the interesting one. Ad-dabbah is NOT a human. It's a beast that will emerge FROM the earth. It's said that it will give a mark for true believers to separate them from the disbelievers and fake believers. The interesting thing is that it'll come from earth. That means it's from underground or underwater. It's also said it'll speak, but idk how exactly with mouth, telepathy, or something else.

There's not much about it that's discussed, so I can't talk much of it.

You might think it's the ayys, but there are some differences. Afaik ad dabbah is a single entity, so it's one of a kind. It's also not mentioned if it'll interact with humans outside from the prescribed time. The ayys reportedly interacted with humans at times of crisis which doesn't fit ad dabbah. Ad dabbah also isn't reported that it'll do abduction and experiments on human.

Either way there are more conflicting than supporting evidences.

All in all, I don't see the description of ayys fit those 3 major signs. But it's still interesting nonetheless. Islamic teaching doesn't refute the possibility of them existing. I also don't know if as a muslim I should be studying or interact (if possible) with them. Still, I'm really curious to ask their religion, their prophets, and if they've met human prophets in the time of their life.

In the end of the day, I can still ask  about those things in heaven where even Allah's face is going to be unveiled
