Abstract

Muʽtazilah is one of the kalām schools in which intellectual freedom is seen the most and therefore divergences within the sect are the most common. Although al-usûl al-ḥamsa/five principles constitute the main framework on which Muʽtazilah has agreed, opposing ideas have emerged within the sect on the principles of ʽadl (divine justice) and al-manzilah bayna al-manzilatayn and on the issues of nature and imamah. As a matter of fact, Muʽtâzilī scholars wrote many refutations to each other on the disputed issues. One of those who have opposing views within the Muʽtazilah is Muḥammad b. Shabīb al-Baṣrī (d. mid 3rd/9th century), who lived between the end of 2nd and the middle of the 3rd century of hijra. Ibn Shabīb is one of the students of Ibrāhīm Ibn Sayyār al-Naẓẓām (d. 231/845), who was one of the leading scholars of Muʽtazilah. He initially opposed the principle of al-manzilah bayna al-manzilatayn, while he was Muʽtezilî, and accepted the Murji’ah approach on this issue. However, after he accepted the idea of irjā’, he continued his loyalty to Muʽtazilah with regard to the principles of tawhīd (divine unity) and ʽadl. Ibn Shabīb, who had a theological assembly of his own and is respected by the people in Baṣra, was an important scholar who stands out with his comprehensive knowledge of religious and philosophical schools of his time. In the doxographical tradition, his adoption of Murjī’ ideas is generally emphasized, except that he has not been referred to much. However, when the sources of kalām are examined meticulously, it is understood that he influenced many Muslim theologians with his works and views and that he was a source for them regarding many topics. The most important reason for this is that he was one of the first scholars to defend the Islamic belief against various philosophical and religious movements. Naturally, this situation provided him with a wide knowledge of religious and philosophical trends. Considering the quotations made from him, it is understood that he recorded this accumulation in a doxographical work. Another remarkable feature of Ibn Shabīb is that he was one of the first scholars to write in the genre of Kitāb al-Tawhīd. It is possible to see both contextual and methodological effects of this work in the quotations and narratives of Al-Māturīdī's book with the same name. What makes him different is that he adopts Muʽtazilī and Murjī’ ideas at the same time and develops a unique discourse on the subjects of grave sins and waʽīd (divine warning). Although he was raised in a strong tradition of thought such as Muʽtazilah, his ability to oppose his sect and his teacher Al-Naẓẓām and also to develop a different definition of faith despite accepting the doctrine of irjā’, makes him stand out as an original and intellectual personality. His different definition of faith is important in that it represents a more moderate approach to the issue of takfīr. For, he drew an encompassing framework based on the Quran and the Sunnah regarding the definition of faith and the conditions of takfīr, thus, he tried to preserve the unity of Muslims. He did not consider the denial of controversial issues that are not explicitly included in the Quran and Sunnah as a reason for takfīr. With this attitude, Ibn Shabīb took an important approach in ensuring social peace and free thought. In this article, all the information contained in Muʽtazilī sources, and doxographical works related to the life, scientific personality and theological views of Ibn Shabīb are gathered and analyzed, and then his theological thought is reconstructed based on these data. From this point of view, identifications and evaluations have been made regarding the issues that make him different and unique in the history of Muslim thought.
