Sometime during the 6th century, the Tayy and the Asad formed a confederation, which was later joined by the Banu Ghatafan as well. The alliance collapsed when Asad and Ghatafan assaulted both the Al al-Ghawth and Al Jadilah and drove them out of their territories in Jabal Tayy. However, one of the leaders of the Asad, Dhu al-Khimarayn Awf al-Jadhami defected from the Ghatafan soon after and reestablished the alliance with the Tayy. Together, they campaigned against Ghatafan and restored their territories in Jabal Tayy.
