Kitab Sulaym ibn Qais Al Hilali is most authentic book written in early era of Islam. According to Imam Sadiq(as), Every Shia should have this book, and they should read this book. If any one doesn't have this book he doesn't have anything from Ahlulbayt(as) and doesn't know anything about the matters of Ahlulbayt(as). This is the urdu translation of the book.
