If u are employeed with a firm (not private bussiness) in Qatar and want to import goods for selling then yes that is against Qatari Laws. But if u are a bussiness man(i.e u own a company) then you have to get a license for import/export license registered in the name of your company. Also it depends on the kind of stuff you are planning to import.

I don't know much about importing for personal use though.

If you can mention what in general u want to import....like if its electronic or some spareparts or something like that....then could give u a more clear idea.
