Travel to Hamadhan
On January 12, 1160, Suleiman Shah traveled from Mosul to Hamadhan. The reason for going to Hamadhan was that after the death of Prince Muhammad, son of Sultan Mahmud, the great emirates sent Atabig Qutb Alaun Maudood, the owner of Mosul, to send Prince Suleiman Shah from them, so that he would be able to do so. Make it a royal investment. An agreement was reached between them that Sulaiman Shah should be the Sultan, Qutbuddin Maudood should be his Atabig, that Jamaluddin, Qutb al-Assad Maudood should be the Vizier, Sulaiman Shah and Zainuddin Ali should be the Vizier Suleiman Shah should be the commander of the army. They all swore to accept it, and Suleiman the Magnificent was equipped with large sums of money, campaign equipment, offerings, autonomous reguli, and the like, which fit the Sultan. He left for Hamadhan with Zaaluddin to lead the Mosul army.
As they approached the hills, the army came to join them, a group and a nobleman would meet them daily, until a large army would gather around Suleiman the Magnificent. Zainuddin considered him a treat because he saw that the Sultan had so much pressure on him and he showed so much respect that his trouble became inevitable. So he returned to Mosul. When he went back and left Suleiman Shah, the plans did not work out and he failed to achieve his wish. The army arrested him at the gates of Hamadhan in October 1160 and made a sermon for Arsalan Shah, the son of Sultan Tughiril II, whose mother was married to Eldkis.
