Where can I find arabic books?
I support @Azbakiyat Amman but keep in mind a lot of the books there are copies. Otherwise, I would say it's worth going on a trip downtown where all the old publishing houses and book kiosks are.
Where can I get Adderall?
I think only Ritalin is available in Jordan and it is only available by prescription.

Try freelancing on Freelancer or PeoplePerHour if you have any skills to work from home.
Where can I find the spicy korean sauce ( Buldak sauce ) and other korean food?
@Asia Market in Jabal Amman
Where can I find Pomegranate & Rose Cordial syrup?
Pomegranate syrup/molasses is sold at any hypermarket or attar. I have never seen Rose Cordial Syrup (Rooh Afza) in Jordan but your best shot would be trying @Asia Market in Jabal Amman across from Abu Jbara
