Your teacher perhaps is not a Muslim. At the moment we are not really prepared to benefit from the expertize these people have. We got to do little bit of home work ourselves. My impression is that we do have enough number of Muslims who have expertize in economic, financial and business issues. Then we have our traditional Islamic scholars. Former have to get some training in Islam - even if they pray five times a day. This training should be about Islamic outlook about on economic, financial and business issues. This has to be provided by the latter - whatever little they have. Our job is to bring every bit of our knowledge and expertize under the supervision of Islam and this can be done only by those who are trained in modern economic, business and finance theories. Can we armchair-key board activists convince any number of modern experts to have a look at this? This is where internal Dawah comes in. There are people who are calling Muslims to the Mosque - Tablighi Jama-at. Where are the people who are calling scientists, economists, financial experts, psychologists to give a thought to the fact that because of their religion they are obliged to submit even their expertize to the will of Allah (SWT)?
