Worship Law: Systematic Comparative Jurisprudence

The worship law sections of Al-Istidhkar represent Ibn Abd al-Barr's systematic comparative jurisprudence at its most thorough. Beginning with the chapters on purification — the traditional opening of Islamic jurisprudential works — and moving through prayer, almsgiving, fasting, and pilgrimage, Al-Istidhkar presents for each major legal question the full array of scholarly positions with their supporting arguments and Ibn Abd al-Barr's own assessment.

The purification chapters document the full range of positions on what constitutes ritual impurity, how it is removed, and under what conditions the simplified dry ablution may be used. Ibn Abd al-Barr's presentation is organized around specific questions — does a particular act require full ablution or only washing of the relevant part? — and for each question he presents the positions of all major schools with their textual bases. His discussions of the specifically Maliki positions are particularly authoritative, drawing on his deep knowledge of the western Maliki tradition.

The prayer sections of Al-Istidhkar are among the most extensively developed in the work, reflecting the centrality of prayer in Islamic life and the large number of contested juristic questions that surround its correct performance. Ibn Abd al-Barr's comparative analysis of the prayer traditions covers all the major points of school disagreement: the precise moments for raising the hands, the placement of the hands during the standing position, the conduct of the imam and the congregation in various circumstances, and the specific rulings on the Friday and special occasion prayers.

The fasting and pilgrimage sections complete the worship law coverage with the same systematic comparative approach. The fasting sections address in particular the conditions under which fasting is excused, the acts that break or do not break the fast, and the expiatory measures for various categories of violation. The pilgrimage sections address the complex question of the precise performance of hajj rites, where early scholars showed significant variation in their accounts of the prophetic practice.
