Zuhayr ibn Qays

Zuhayr ibn Qays al-Balawī was a companion of the Islamic prophet Muhammad and an Arab commander who fought in the service of the Rashidun, Umayyad and Zubayrid caliphs. He played a key role in the early Muslim conquests of Egypt, Barqa (Cyrenaica) and Ifriqiya. When the latter province fell to a Byzantine–Berber alliance in 682, Zuhayr was given command of the army to restore Arab rule. During that campaign, he temporarily retook Kairouan, the Arabs' capital in Ifriqiya, and killed the Berber chief Kasila, but was slain by Byzantine raiders on his way back to Barqa.
