Dr. Osman was recognized as a pioneer contemporary Islamic thinker. He wrote on Shari’a in contemporary society, human rights, women in Islam, pluralism, the "other", the permanent and transitional in the sacred sources, Shura and democracy and on other contemporary issues of the time. His "Concepts of the Qur’an: A Topical Reading" was an important work that enabled English speakers to understand the Qur’an. "Contemporary Issues: An Islamic Perspective" and the "Other" are his latest major publications.
The term "fiqh alaqaliyat" (jurisprudence for minorities) was coined by Dr. Osman with the fundamental objective of allowing Muslim minorities, especially in the West, to be practicing Muslims complying with Islamic law and full citizens active in all aspects of life in the land where they live.
Dr. Osman is succeeded by his wife, Dr. Aida and daughter, Dr. Ghada Osman. IIIT extends condolences to his family, his colleagues and students all over the world. His death is a loss for the whole Ummah, but the legacy he left will be a shining example for generations to come on the dedication of a scholar and sincerity and service of an engaged intellectual.
