This book is a translation of Muhammad 'Abduh's Al-Islam wa-l-Nasraniyya ma'a al-'Ilm wa-l-Madaniyya (Science and Civilization between Islam and Christianity) 'Abduh is an Egyptian jurist, religious scholar, theologian and a reformer of Al-Azhar who died in 1905. His impact on modern Islam cannot be overstated. In fact, much of modern Muslim thought has either been a reaction for or against his ideas. Although numerous English studies have been done on him, only one treatise of his has been translated into English. That is, Risalat al-tawhid (Theology of Unity) by Ishaq Masa'ad and Kenneth Cragg, in 1966. Far too little attention has been paid to the treatise translated here. Much less attention has been given to how this treatise impacts the Islamic theology of Christianity. Hence, this translation fills a serious gap in the genre of Islam and Christian-Muslim Relations.
