Book excerpt: Aqeedah Tahawiyyah, though small in size, is a basic text for all times, listing what a Muslim must know and believe and inwardly comprehend. There is consensus among the Companions, the Successors and all the leading Islamic authorities such as the four Imams and their authoritative followers on the doctrines enumerated in this work, which are entirely derived from the undisputed primary sources of Religion, the Holy Qur'an and the confirmed Hadith. Being a text on Islamic doctrine, this work sums up the arguments set forth in those two sources to define sound belief, and likewise, the arguments advanced in refuting the views of sects that have deviated from the Sunna.As regards the sects mentioned in this work, familiarity with Islamic history up to the time of Imam Tahawi would be quite helpful. More or less veiled references to sects such as the Mu`tazila, the Jahmiyya, the Karramiyya, the Qadariyya, and the Jabariyya are found in the work. It also contains allusions to other views considered unorthodox and deviant from the way of Ahl al-Sunna. There is an explicit reference in the work to the controversy on the creation of the Qu'ran in the times of al-Ma'mun and others.While the permanent relevance of the statements of belief in the `Aqida are obvious, the historical weight and point of certain of these statements can be properly appreciated only if the work is used as a text for study under the guidance of some learned person able to elucidate its arguments fully, with reference to the intellectual and historical background of the sects refuted in the work. Since the present book is intended exactly as one such aid towards understanding the details of Islamic belief with clarity, it is hoped that the quotation of the entire text of Tahawi's "Doctrine," which we consider as the doctrine of Ahl al-Sunna wa al-Jama`a, will be of benefit to the reader. And may Allah grant us a true understanding of faith and count us among those described by the Prophet as the Saved Group.
