[5] Yazid recited a verse in one of his poems that "They [the Amir] left the brother of al-Nu'man walking in [shackles as a captive] and mutilated the troops of the king".

[5] During a raid by the Banu Amir against the Banu Tamim at a place called Dhu Najab near Wadi al-Rummah, Yazid was struck in the head by an opposing tribesman and died of his wound.

[6] A son of Yazid ibn al-Sa'iq, Mu'adh, opposed the defection of his tribesmen from the early Muslim state during the Ridda wars.

[7] Among Yazid's other descendants were Zufar ibn al-Harith al-Kilabi, a leader of the Banu Amir and the larger Qays confederation in Syria in the late 7th century.

Yazid was a chieftain of the Amr branch of the Banu Kilab . His descendant Zufar ibn al-Harith al-Kilabi was preeminent chief of the Qays tribal faction in Syria during Umayyad rule.
