This will get moved to the equipment section by the moderator.

First get started with 10x50 binoculars and a good book and charts for them. That way you can learn the sky. Until you do the telescope is mostly useless as you don't know where to point it or what it can and can't do.

In the equipment section read Dave's sticky note (2nd from the top) about binocular astronomy for help here.

Next I'd normally say to look up your local astronomy club. There is one listed for Dubai but its website seems far more interested in fanatic religious causes than astronomy so I'm not sure how useful it is. Check it out if you wish.

They claim 500 members. I much prefer smaller clubs but that's all I see listed for your town. Two small ones apparently exist in Abu Dhabi

If it really is a useful club they'll hold star parties where you can learn about telescopes first hand (far better than reading about them) and and start to get an idea why there are so many different ones and which does what you are most interested in.

There are many threads in that section about getting started. Pay particular attention to the moderator's (Dave Mitsky) links in these threads for good information. That's not to say others don't have good information too, just that without any knowledge you don't know which few (very few) are poor. Once you've digested those then go on to the others.
