Kitab e Sulaym ibn Qays Al-Hilali

Imam Ja€far Al Sadiq (a.s) said:
€œIf anyone from our Shia and devotees does not have the book of Sulaym ibn Qays al Hilali, then he does not have any of our things, and he does not know any of our matters.This is the first book of Shia and is one of the secrets of Ale-Muhammad (a.s)€
