Authored in the eleventh century, al-Nihayah remains a jurisprudential classic. Initially written as a shariah guide to issues as diverse as ritual worship, business transactions, and civil law, it offers the modern reader a unique insight into early Shia Islamic jurisprudence as well as the habits and customs of the Muslim world at the time. Written by one of the pioneers of the development of the Islamic legal system, Sheikh Mohammad ibn Hasan ibn Ali Abu Jafar al-Tusi, this work was recognised as one of the major early sources of, references for, and textbooks on Islamic law in the Shii school of thought. An excellent reference book and textbook for studies in Islamic law.
