Dear Engr Bhai,
Your headline gave me an impression it will be about world economics as per Quran, but it wasn't to be.
Kindly refer us a comprehensive work of quranic economics with which nations may run the present and future world ( not past) since life is about present and future.
Every one talks about quranic economics or sharia society, no one can find a system or comprehensive work in this field. Muslim don't work, they go for cooked food only.
The word Quranic economics is wrong and inapplicable, Quran is about personal character kindness, justice, fear/rewards of post life and order in a just society.
You run the economics with your given wisdom and not under a divine books. Lets not swim in the holy book for every thing, but use our god given wisdom which is also a gift from Allah, the greatest gift which made us mankind.
