Dr. Muhammad Hamidullah was a genius and prolific writer. Anyone who has an interest in the Qur'ans translation, Hadith literature International Islamic Law, Islamic Politics and archival heritage of Islam cannot ignore Dr. Hamidullah's contributions. He started writings on the subject of Islamic Economics as early as the 1930s. He was a pioneer in Islamic economics and many firsts in this subject belong to him. For instance: interest free financial institutions in the modern period, advocacy of mutuality as the basis for Islamic insurance, mutuality based Islamic finance and proposal for establishment of international interest-free monetary fund. He also critiques current systems and offers an alternative. His works are also a rich source of Islamic economic history. None of his contemporaries in the first half of twentieth century had written on such a diverse aspect of the subject.
