Renowned for his scholarly contributions, he authored the influential work Kitāb al-Kāfī, which remains a cornerstone in Shia Islamic literature.

His quest for knowledge took him on extensive travels, particularly to the cities of Qom and Baghdad, where he sought to gather hadith from various sources.
