Sharif al-Murtadha

Al-Sharif al-Murtada lived during the era of the Shia Buyid dynasty of Daylamite origin, which came to rule over Iraq and parts of Iran in 934–1062, which also coincided with the golden age of Arabic literature, and great poets al-Ma'arri were among his contemporaries. His prominence as a Shiite authority is also evident in the outreach of his letters, which addressed inquiries of Shiite communities (masā'il) in Tiberias, Tripoli, Sidon, Mosul and Aleppo.

Training under Shaykh Saduq and Al-Shaykh Al-Mufid is recorded. Shaykh Tusi, Abū al-Ṣalāḥ al-Ḥalabī and Sallār al-Daylamī are recorded as having studied under Sharif al-Murtadha. The recorded working language is Arabic. Works named in the authority record are Ghurar wa-al-durar and Al-Dhari'a ila Usul al-Shari'a.

His full name was "Ali ibn al-Husayn ibn Musa ibn Muhammad ibn Musa ibn Ibrahim ibn Musa al-Kazim" (Arabic: علي بن الحسين بن موسی بن محمد بن موسی بن ابراهيم بن موسى الكاظم).

Ali ibn al-Husayn was born in Baghdad in Rajab 355 AH (June/July 966 CE) to Abu Ahmad al-Husayn ibn Musa, a fifth generation descendant of seventh Twelver Shia Imam, Musa al-Kazim (745–799). He was the naqib al-ashraf at his time. His mother was Fatima, the great-granddaughter of Zaydi Imam, Hasan al-Utrush, the ruler of Alavid Tabaristan (864–928). She was a pious and noble lady, who was held in high esteem by scholars and other notables. At her request, the great scholar Shaykh al-Mufīd compiled the book "Ahkām al-Nisā'", which contains the fiqhi rules for women. His father called him Ali, and his nickname was Murtada. His honorific title was 'Alam al-Huda (Arabic: علم الهدى). He was reportedly called as such according to a popular narration by Muhammad ibn Makki, when an Abbasid vizier called Muhammad ibn al-Husayn was told in a dream by Imam Ali to seek 'Alam al-Huda, and when asked on his identity, informed him it's Sharif Murtada.

Since he was the pupil of both Qadi Abd al-Jabbar the Mu'tazilite and al-Shaykh al-Mufid, he was influenced by both of them. He even criticised them.

According to Sharif al-Murtada, the first part of religious duty is the obligation to reason to the knowledge of God. The other duties are dependent on this first duty. Al-Murtada along with the Mu'tazilite starting-point is the claim that man's first duty is to use his reason to arrive at the knowledge of God. Also in Kalam there is proof of the existence of God, he defended the atomist' stance versus that of the Aristotelian notion of substantial change.

Sayyid Murtaḍā acquired the epithet of: "ʿAlam al-Hudā" ("The banner of guidance"), and died at the age of 81 years in 1044 (436 AH).

He was a multi-dimensional personality. All Shi'ite scholars acknowledge that Sayyid Murtaḍā was the greatest scholar of his era, and groomed many outstanding ulama (scholars), including the famous Shaykh al-Tūsī, the founder of the celebrated theological Center of Najaf. He served as "Naqīb al-Nuqabā'" after the death of his brother. Sayyid Murtaḍā was deeply interested in fiqh, unlike Sayyid Raḍī, who was more inclined towards politics and literature,. He was considered a master of kalam, fiqh, usul al-fiqh, literature, grammar, poetry and other fields of knowledge. His divan or poetry collection has more than 20,000 verses. Books authored by Sayyid Murtaḍā include: al-Dhakhīra fī Uṣūl al-Fiqh (الذخيرة) al-Ghurar wa al-Durar (الغرر والدرر) al-Intiṣār (الانتصار) al-Shāfī (الشافي) Tanzīh al-Anbiyāʾ (تنزيه الأنبياء) Jumal al-ʿilm Wa al-ʿAmal.
