Your spouse applies and you sponsor him. If he applies in Qatar, you must be returning to UK with him, and if you are relying on your income, you must be currently in a job earning at least £18,600 and you have a UK job offer starting within 3 months of returning. If you aren't currently earning, you must return to UK first and work for at least 6 months before you can sponsor him. If you have savings worth £62,500, you don't need current job or job offer.
The only way for you to go to UK together is if you are currently in a job in Qatar earning £18,600 minimum and you have a UK job offer. Or you have savings to the set amount. Or your husband can qualify for a visa in his own right, such as study or sponsored work.
