That is indeed a good point. I see Mohammed (PBUH) and his first wife of good examples of basic market economics (which is all normal capitalism is). However today, we have vastly different forms of capitalism in the form of mega-corporations and stock markets that are based on religious-like "faith" in infinite economic growth while in a world of limited finite resources. As such the current Western capitalist system is not based upon sustainable economics. They are based upon short-sighted economic theories that people have blind-faith in. I am not saying that the solution is socialism either. Extremes of socialism are just as dangerous as we have seen in world history. It is in this area, that I do believe that a form of Islamic capitalism could fill in the gap between Western capitalist extremes and Socialist extremes. I know some Turkish companies practice Islamic values and I am sure that many do in other parts of the Islamic world. These are the types of Islamic ideas that I wish more Shaykhs would study and advocate rather then simply rant against Western global economics. If these Islamic forms of capitalism can catch on regionally, they could spread globally as Western economies collapse from their own greed and short-sighted economic policies (mainly based on imaginary "future money"). Unfortunately however very few Shaykhs study comparative economics as that is often lumped into "kufr" ideology. But without a strong understanding of economics, it leaves many Muslims at the mercy of those who do have a better understanding of economics, but who are not interested in doing what is best for Islam. At rate, if anyone knows of any Shaykhs who have tried to develop a form of economic theory based upon Islam, I would be very interested in studying that.
