تفسير التحرير و التنوير 12 مجلد

Muhammad al-Tahir ibn Ashur was born in Tunis in 1879 to an affluent family and died in 1973 at age 94. He was of Andalusian origin. The family had shown dedication to the pursuit of knowledge for generations. His grandfather was especially renowned. When he entered Zaytuna, care was made to provide him with the best teachers. He was a teacher at Zaytuna all his life. His masterpiece is the Maqasid al-Shari'ah al-Islamiyyah, the Intents, or Higher Goals of Islamic Law, published in 1946. He is famous for rejecting Habib Bourguiba's (president of Tunisia) request for a fatwa to justify abandoning the fast of the month of Ramadan claiming it harmed productivity. He responded by stating "Prescribed for you is fasting", and announced on the radio, "God has spoken the truth and Bourguiba has spoken falsehood." He was, as a result, dismissed from his post.

Influenced by a visit to Tunisia by Muhammad Abduh, Ibn Ashur combined knowledge of the classics with a desire to revive Islamic civilization. He positioned himself as a bridge between the classical Islamic legal heritage and the needs of a modern world. His references to the great works of law are respectful and at times praiseworthy, but he does not hesitate to point out shortcomings. Responding to modern challenges to Islamic traditions, Ibn Ashur called for substantive reforms in Islamic education. His work on the ultimate purposes of Shari'a represented an attempt to revive the maqasid theory of Shatibi and an effort to renew Islamic legal theory.
