One of the early Muslims from the righteous followers of the Sunnah was Qanbar (RA).
Qanbar was a young black male, who was freed from slavery by Imam Ali bin Abi Talib (KW). Qanbar is written about in several books relating to his person to narrations with him mentioned them; some of those who mentioned him are Abdur-Razzaq As-San’ani, Abu Ya’la Al-Musuli, At-Tusi, Al-Mizzi and ibn Hajr Al-Asqalani. Moreover, he is referenced as being one of the closest followers of Imam Ali (KW) during his government. He was in Al-Kufah, Iraq during the khilafah of Imam Ali (KW) when Imam Ali (KW) was martyred.
Qanbar was a man who stuck closely to the truth and spoke out against oppression. Due to his noncompliance with the oppression of Bani Umayyah after the martyrdom of Imam Al-Husayn (AS), Qanbar was martyred by the brute governor of Iraq named Al-Hajjaj bin Yusuf, a man who was also responsible for the martyrdom of the great black tabi’i named Sa’id bin Jubayr (RH).
