Shaykh Tusi was a highly influential Twelver Shia Muslim scholar. He was a master of many different fields of study. These included jurisprudence, which is the study of religious law. He was also a theologian, a mufassir, and a compiler of hadith. Hadith are the recorded sayings and traditions of the Prophet. Tusi was of Persian descent. Many people gave him the title Shaykh al-Ta'ifah. This title shows the great respect people held for him.

Tusi's life was marked by deep learning and significant historical changes. He was born in 995 AD in Tus, Iran. He began his education in his home city of Tus. Later, he moved to Baghdad to continue his studies. In Baghdad, he joined the learning circles of al-Shaykh al-Mufid. He also studied under Shaykh Murtaza. By age forty-two, he had studied many different Islamic sciences. He even studied the Shafi'i school of fiqh with Sunni scholars.

History brought great challenges to Tusi during his time in Baghdad. In 1055, the Seljuk dynasty captured the city. This event caused sectarian fighting between Sunnis and Shiites. Many mosques and libraries were destroyed during this conflict. Tusi's own house was burned down. He lost many of the books he had written. Because of these events, he relocated to Najaf. This move changed the course of his life and his work.

In Najaf, Tusi focused on reviving religious knowledge and law. Some scholars believe he founded the Hawza of Najaf. The Hawza is a major seminary for religious learning. Tusi was very productive as an author. He wrote over fifty works on many subjects. These subjects included philosophy, history, and exegesis. Exegesis is the critical explanation of religious texts. Two of his books are extremely important to Shia Muslims. They are Tahdhib al-Ahkam and al-Istibsar. These books are part of the Four Books of Shia hadith.

Tusi played a major role in shaping the Usuli school of thought. He defended the Usuli approach against the Akhbari school. He argued that the Akhbari were literalists. Tusi believed in using the principles of jurisprudence to reach judgments. He also strongly refuted the use of legal analogy, known as Qiyas Fiqhi. He emphasized that reason is a vital part of religion. He believed that reason shows why people must do good and avoid evil.

One of Tusi's most important ideas involved the role of reason in faith. He used rational arguments to support the concept of consensus, or ijma. He connected this to the principle of lutf. According to this principle, God provides the conditions for religious obedience. This helped clarify how religious laws should be applied. Tusi also helped develop new roles for Shia clerics. They could now collect religious taxes and organize Friday prayers. These were tasks previously reserved only for imams.

Tusi's intellectual dominance lasted for a very long time. Most Islamic jurisprudence was affected by his many opinions. His influence continued until the time of Ibn Idris al-Hilli. Al-Hilli eventually criticized some of the views held by Tusi. Even so, Tusi's methodology remained a foundation for others. He produced biographies, known as ilm-rijal, and other compendia of knowledge. His work helped make the methodology of inference more coherent. He died in Najaf on December 2, 1067.
