[3] One of his slaves was Badr ad-Din Lu'lu', who became a famous ruler of Mosul, and a prominent patron of the arts.

[3] In 1204, Saladin's brother and successor, the Ayyubid ruler Al-Adil I, dispatched an army under the leadership of his own son al-Ashraf of Harran, accompanied by his brother Al-Awhad Ayyub, to relieve the Zengid emir of Sinjar, Qutb al-Din, from an assault by his cousin Nur ad-Din Arslan Shah I, who was the chief Zengid emir.

In April 1204 the Ayyubid coalition swiftly defeated Nur ad-Din's forces at Nusaybin, chasing them back to Mosul where they attacked several of the surrounding villages.

They reached a truce, according to which al-Adid could retain the lands he conquered in Sinjar (thereafter ruled by the "Ayyubids of Mayyafariqin & Jabal Sinjar", the sons of al-Adid al-Ashraf and Al-Awhad Ayyub), and Arslan Shah would recognize Ayyubid suzerainty on his coinage.

[5] The son and two grandsons of Arslan Shah continued to rule as children in Northern Iraq as Emirs of Mosul and Sinjar until 1234, when Badr al-Din Lu'lu' formally took over, possibly after assassinating the last Zengid Emir of Mosul Nasir ad-Din Mahmud.
