Book excerpt: Originally published in 1966, this was the first of Muhammad ‘Abduh’s works to be translated into English. Risālat al Tauhid represents the most popular of his discussion of Islamic thought and belief. ‘Abduh is still quoted and revered as the father of 20th Century Muslim thinking in the Arab world and his mind, here accessible, constituted both courageous and strenuous leadership in his day. All the concerns and claims of successive exponents of duty and meaning of the mosque in the modern world may be sensed in these pages. The world and Islam have moved on since ‘Abduh’s lifetime, but he remains a source for the historian of contemporary movements and a valuable index to the self-awareness of Arab Islam.
