Sulaym ibn Qays al-Hilālī al-ʿĀmirī (Arabic: سليم بن قيس الهلالي العامري, died before 714, was one of the Tabi‘un and a companion of Ali towards the end of the latter's life. Sulaym was also a loyal companion of Ali's sons Hasan and Husayn, the latter's son Ali Zayn al-'Abidin, and Muhammad al-Baqir. He is the purported author of an early Shi'ite hadith collection, the Kitab Sulaym ibn Qays ('The Book of Sulaym ibn Qays'), the attribution of which to Sulaym is generally considered false. Scholars also dispute whether he ever existed as a historical figure. Source: Wikipedia (en)
