I don't know anything about Arabic astrology.
Chiron I believe is considered an asteroid, is the only one I am slightly familiar with. It is in my 10th house (along with my sun), in Taurus. Chiron symbolizes healing as a major theme from my understanding. My natal chart doesn't really go into it in detail though.
It's interesting you bring up asteroids in a natal chart, something not spoken of often in Western Astrology from my experience (which is definitely limited though). Since watching the first few videos of the Legends of Atlantis series I've been wondering about the mention of the planet between Mars and Jupiter that supposedly crumbled, and created the asteroid belt. There are so many pieces... if it were true that it once was a planet, would all those pieces hold that same energy of whatever that planet may have I wonder?
