Sulaym Ibn Qays

Sulaym ibn Qays (Arabic: سليم بن قيس‎) was one of the purported companions of Ali but he "is widely considered an anti-Umayyad polemical invention" by Sunni scholarship. He has a well-known book known as The book of Sulaym ibn Qays. As Ibn al-Nadim says and later investigation shows his book is "the oldest surviving Shi`ite book" which is written in the first Islamic century.
