The volume examines the impact of crises on the formation of the á¹abaqÄt genre. It demonstrates how á¹abaqÄt, dedicated to explicating religious authority, were used by authors to sort-out challenges to intellectual orthodoxies. It also examines in detail the ṬabaqÄt directly, demonstrating Ibn QÄá¸Ä« Shuhbah’s depiction of the development of ShÄfiʿī law, the formation of intellectual sub-schools within the madhhab, the causes of legal decline, and curatives for the decline that are to be found in the great ShÄfiʿī IkhtilÄf (divergent opinion) texts: the Ê¿AzÄ«z sharḥ al-wajÄ«z by al-RÄfiʿī and the Rawá¸Ät al-á¹ÄlibÄ«n by al-NawawÄ«.
