Passage: Zuhayr belonged to the Bali tribe, itself part of the larger Quda'a confederation that was present throughout Syria and the northern Hejaz. He is considered by some Muslim sources, namely Ibn Hajar and al-Suyuti, as a sahabi (companion) of the Islamic prophet Muhammad, while al-Suyuti also places him with the second-generation of Muslims, known as the tabi'un. According to Ibn Hajar, Zuhayr participated in the Muslim conquest of Egypt in 639. He later served as a lieutenant commander in the army of Uqba ibn Nafi during the Muslim conquest of the Maghreb in 670. In that campaign, he played a role in the capture of Sirte and was made its governor. The Arabs established the town of Kairouan in Ifriqiya to garrison their troops and families and when Uqba advanced west of Kairouan, Zuhayr accompanied him. As Uqba campaigned in the region of Sous (in modern-day Morocco), he ordered Zuhayr to return with the majority of the Arab troops to Kairouan to defend the city from an impending Byzantine attack.
