Muslim ibn al-Hajjaj al-Qushayri (c. 815–875 CE), commonly known as Imam Muslim, was a prominent Islamic scholar and hadith compiler during the Abbasid era. Born in Nishapur, Iran, he dedicated his life to the study of hadith, the sayings and actions of the Prophet Muhammad. Imam Muslim is best known for his compilation of authentic hadith collections, particularly the "Sahih Muslim," considered one of the most authoritative collections of hadith in Sunni Islam. His rigorous methodology in verifying the authenticity of hadith and his meticulous attention to detail earned him widespread recognition and respect among scholars. Imam Muslim's work remains an essential reference for scholars and practitioners of Islam, shaping Islamic law and theology for centuries.
