Oh sorry, I meant students not Imam. And thanks for mentioning those books. I didn't even know our imams left behind any written work. Anyways, I'm just wondering if we have any major books on shia fiqh before Al-Kafi but obviously writing such things down while the Imams were openly accessible wouldn't have been a big issue but it could be used against us. The conspiracy theories abound about shia origins etc. I've even heard sunnis claim that shias completely made up Jafari fiqh and Malik ibn Anas' fiqh is the real jafari madhab endorsed by the Imam so im wondering if the Imam had any other students who wrote his sayings and rulings down before Al-Kafi was compiled.
