Introduction to Al-Wajiz by al-Ghazali

Al-Wajiz fi Fiqh al-Imam Al-Shafi'i ('The Concise Work in Shafi'i Jurisprudence') is a compact but comprehensive legal manual authored by one of Islam's greatest scholars, Abu Hamid Muhammad ibn Muhammad al-Ghazali at-Tusi (450–505 AH / 1058–1111 CE). Al-Ghazali's multidimensional genius — as a theologian, philosopher, Sufi master, and jurist — makes him unique in Islamic intellectual history, and Al-Wajiz reflects the Shafi'i school's rulings as understood by one of its greatest expositors.

Al-Ghazali was born in Tus (in present-day Iran) and studied under the leading Shafi'i scholars of his time, most notably Imam al-Haramayn Abu al-Ma'ali al-Juwayni (d. 478 AH) at the Nizamiyyah school in Nishapur. He later came to Baghdad, where he taught at the Nizamiyyah school and became the most celebrated scholar of his era. His celebrated spiritual crisis, resignation from teaching, and decade of travel and contemplation are documented in his spiritual autobiography, al-Munqidh min ad-Dalal ('Deliverance from Error').

Al-Ghazali's fiqh output includes Al-Wajiz, Al-Wasit (a middle-length work), and Al-Basit (his most extensive fiqh work). These three form a trilogy of increasing elaboration on Shafi'i law. Al-Wajiz is designed for students who have mastered the basics and want a reliable compact reference covering the full range of Shafi'i rulings. It became one of the primary teaching texts of the Shafi'i school and attracted important commentaries, most notably Al-'Aziz Sharh al-Wajiz by ar-Rafi'i (which itself became the basis for Al-Nawawi's Rawdat at-Talibin).

Al-Ghazali's theological position was broadly within the Ash'ari school, and his relationship between philosophy and religious knowledge was complex and evolved throughout his career. In his fiqh works, however, he adheres strictly to Shafi'i legal methodology without importing philosophical concepts. Al-Wajiz is a pure fiqh text, reflecting the Shafi'i school's positions with precision and clarity.

Beyond his fiqh works, al-Ghazali is best known for Ihya' 'Ulum ad-Din ('The Revival of the Religious Sciences'), a monumental work integrating law, theology, ethics, and spiritual development. His position in the Islamic intellectual tradition is that of a scholar who simultaneously mastered the external sciences ('ulum adh-dhahir — fiqh, theology) and sought to integrate them with the internal sciences ('ulum al-batin — spiritual development). This integrated vision informs his approach to fiqh even in Al-Wajiz, where the legal rulings are always implicitly connected to their spiritual purposes.
