Umar Ibrahim Vadillo was born in 1964. After attending the Augustinian College in Navarre he went to study agronomy at the University of Madrid. While still at university he embraced Islam. There followed a long period of study applying the commercial parameters defined in Islam’s founding legal document Imam Malik’s Al Muwatta, to modern financial practice. This led to his studies on Zakat, which implied the necessary use of the Islamic Gold Dinar and Silver Dirham. He has lectured extensively in various universities, notably in Morocco, Malaysia and Indonesia.
