Kaʿb ibn Zuhayr (Arabic: كعب بن زهير) was a pagan in the time of Muḥammad, the eldest son of Zuhayr ibn Abî Sûlmâ, and one of six men who refused the prophet's attempts to convert them.
Presenting a poem entitled the Banat Su'ad to the Prophet, he was rewarded with the mantle that Muhammad was wearing (the burda), and converted to Islam.
