This volume examines Islamic maritime law and practice of Muslim mariners during the classical period using Fatwa and Geniza sources. Maritime terminology, interrelationships of mariners, maritime commercial and military laws, territorial waters and the performance of Islamic religious duties at sea in the period are discussed.

Ritual and practice are one of the most distinctive features of religion, and they are linked with its central beliefs. Islam is no exception here, and this Handbook covers many aspects of those beliefs and practices. It describes the variety of what takes place but mainly why, and what the implications of both the theory and practice have for our understanding of Islam. The book includes accounts of prayer, food, pilgrimage, mosques, and the various legal and doctrinal schools that exist within Islam, with the focus on how they influence practice. The volume is organized in terms of texts, groups, practices, places, and others. An attempt has been made to discuss the wide range of Muslim ritual and practice and provide a sound guide to this significant aspect of the religious life of one of the largest groups of believers in the world today.

Under the supervision of Ayatullah Ja'far Subhani, Sayyid Rida Husayni Nasab introduces a text outlining the differences in different 'Ummahs' of Islam. He discusses what unites them, as well as those traditions and understandings that cause dispute amongst them.
