Al-Kafi is a significant collection of hadiths in Shia Islam, compiled by the renowned scholar Sheikh Abu Ja'far Muhammad ibn Ya'qub al-Kulayni. It is divided into three main sections: Usul al-Kafi, which deals with theological principles; Furu' al-Kafi, focusing on practical laws; and Rawdat al-Kafi, containing miscellaneous traditions. This work is highly regarded for its comprehensive coverage of Islamic teachings and is considered one of the four major hadith collections in Shia tradition. Al-Kafi serves as a vital resource for scholars and followers seeking guidance on various aspects of faith and practice.
