With the GM's sale on at the moment I decided to complete my collection of Al-Qadim PDFs from the DMs Guild. I never actually got to play this setting, but I absolutely love it.
You have revealed yourself to be an adventurer of taste and culture.
Jeff Grubb, the author of a lot of Al-Qadim materials has an interesting behindg-the-scenes reminisce here:

Al-Qadim is the One, True Way to play AD&D 2E. I will die on this hill. But then, my prejudices are well known.
The college gaming group played AQ the year Arabian Adventures came out. One suite-mate was taking an Islamic law class, had never DM'd before, and was inspired. It was lightning in a bottle, and we spend the next 4 years trying to recapture it with various AQ campaigns. Overall, we did; good times, good times.
Fast forward a few years, and I picked up a post-college gaming group. I conned them into letting me try an Al-Qadim campaign. I was successful enough we've come back to it off and on for the last 26 years. Two of them have also run Al-Qadim adventures, so I even get to play sometimes!
I envy you being able to discover this for the first time. Enjoy your reading!
