Ammar ibn Yasir
It is documented that Sulaym moved to Medina during the caliphate of Umar. He is among the people who never met Muhammad. While in Medina, Sulaym became very attached to Imam Ali. His attachment led him to become a partisan of Ali, along with Abu Dhar al-Ghifari, Salman al-Muhammadi, Miqdad ibn Aswad, and Ammar ibn Yasir. Ibn al-Nadim stated that Sulaym ibn Qays was among the devout companions of Ali in his book about the early Muslim scholars and "hadith" contributors.
