Timeless and judicious, originally written in Arabic, it examines the role Islam played in history and its impact on human progress and the loss that humanity suffered by its decline. It counters the prevailing attitude that Islam is a spent force, that it has outlived its usefulness. The author persuasively argues for the eternal reality of Islam and that it is a programme of life which is always dynamic and can never grow obsolete. This thought-provoking tour de force throws new light on the motives, opportunities and impact of the Islamic and other civilisations, on the material welfare and spiritual progress of humanity.
