When it comes to investing, you may have to check your own investment targets first as with any good investor would do. What's your:
1. short (months or less than 1year),
2. medium (1-2 years), and
3. long (5 and or years) term investment goals.

Once you've established that, then determine how much risk you're willing to take and that means, in simple terms, what losses are you willing to forego against rewards or gains.

Below are my recommendations:
1. Short Term: Stocks (choose carefully) and fixed income (at least 5.5% in Qatar)
2. Medium Term: banking and property stocks plus fixed income and maybe a small residential "free hold" property which you may sell while still in financing after 2 years.
3. Long Term: Good long term stocks (check with your broker) and maybe if you've liked the country long enough with finally having stable laws then go for a free hold house that you might want to live in.

That's it for now. Remember, in investing, it is when the markets are irrational that gives you the opportunity to make money... Risks are always there. It's just a matter of prudence and a bit of "intestinal fortitude" to get the rewards...

Cheers and good investing to you.
