This book offers the only detailed presentation available in English of the theory of Muslim law (usul al-fiqh). Often regarded as the most sophisticated of the traditional Islamic disciplines, Muslim jurisprudence is concerned with the way in which the rituals and laws of religion are derived from the Qur’an and the Sunna — the precedent of the Prophet. Principles avoids the use of unnecessary technical expressions and endeavors to use Western legal terms whenever these are appropriate, while remaining close to the Arabic sources.
