<blockquote>I need MBA to be a teacher</blockquote>
Interesting - is an MBA a specific requirement for the teaching jobs you're looking at?

A couple of things to help guide your thinking:

Islamic finance is a very new specialization, so only a handful of schools offer it now. Many of the most reputable schools that even offer classes in this field are in the UK - look into Cass, Durham, and Aston to start with. And getting a part-time job in the UK may be tricky (assuming you'd be registering as an international student.)

Also, do you have at least three years of work experience? If not, maybe wait until you do.

If you specifically want to teach Islamic finance, then an MSc or PhD might be a cheaper and more effective route.
