Isḥāq al-Kulaynī Al-Rāzī (Arabic: <span dir="RTL">ابوجعفر، محمّد بن یعقوب بن اسحاق الرازی</span>) (c. 255/868-9 - 329/941) was among the greatest Shi'a hadith scholars and the author of al-Kafi, the most authentic Shi'a hadith collection and one the Four Books. He was born after the martyrdom of Imam al-'Askari (a), at the time of Imam al-Mahdi (a) and met some hadith transmitters who directly had heard hadiths from Imam al-Hadi (a) and Imam al-'Askari (a). It is said that al-Kulayni was very accurate in transmitting hadiths. Ibn Qulawayh, Muhammad b. Ali Majilawayh al-Qummi, Ahmad b. Muhammad al-Zurari were among his students.</p>
