Only the intervention of veterans of the Aleppo army, who refused to take part in the fratricide war which would weaken the effort against the Crusaders and the Emirate of Damascus, forced Nur al-Din to renounce to the expedition and to reconcile with his brother.

Qutb al-Din Mawdud participated to the Siege of Baghdad (1157) in a coalition with the armies of the Seljuq Sultan Muhammad of Hamadan.

During his reign in Mosul, Qutb held the Seljuq prince, Suleiman-Shah b. Muhammad b. Malik Shah, as a prisoner until 1160.

When he found himself in a weak situation, Nur al-Din launched an expedition against the Principality of Antioch to divert the Christian forces.

The Artuqid emirs of Mardin and Diyarbakır, as well as Mawdud, joined him in the attack, which turned to be successful: the towns of Harim and Banias were captured, and Amalric had to abandon Egypt.
