Abū al-Ḥasan Muḥammad bin al-Ḥusayn bin Mūsā al-Abrash al-Mūsawī (Arabic: ابو الحسن محمد بن الحسين بن موسى الأبرش الموسوي; 970 – 1015), also known as al-Sharīf al-Raḍī (Arabic: الشريف الرضي) was an Iraqi Shia scholar and poet.

[4] He also founded a school named Dar ul'Ilm (Arabic: دار العلم, literally House of knowledge) in which he trained many students.

[5] He devoted twenty years of his life in compiling Nahj al-Balaghah, and traveled to many libraries to collect texts that had recorded the lectures, letters, and sayings that Ali had written or delivered on different occasions.

[citation needed] The book is a collection of sermons, precepts, prayers, epistles, and aphorisms of Ali and compiled by al-Radi in the tenth century.

[12] Collected sermons in the Nahj al-Balagha mainly cover Islam and the Quran; humans and humanity; theology and metaphysics; path and worship, including prayers; social justice and administration; wisdom and admonition; prophecies; philosophy and critique over contemporary society; Ahl al-Bayt; and piety and the afterlife.

[13][14] However, critics of the Nahj al-Balagha generally raise two objections: they claim that al-Murtada is the actual author, and most of the contents are falsely attributed to Ali.

His son was also a prominent scholar of his time and after death of his uncle the official post of Naqib al-Nuqqab was entrawarded to his grandfather.
