Ismail promised to come as soon as he could equip his forces, but meantime, he would send his son al-Mansur Mahmud with a small contingent.
[3] Eventually Ayyub began to grow suspicious of Ismail's perceived procrastination and sent a noted physician, Sa'd al-Din al-Dimashqi, to find out what his vassal was doing.
When he felt ready enough, he requested from Ayyub the return of al-Mansur Mahmud to Baalbek where he would administer affairs while he was absent on the campaign for Egypt.
The Crusaders would secure the southern border of Palestine from Ayyub, while Ismail was forced to effectively cede all of the land west of the Jordan River that Saladin had gained for the Ayyubids in 1187, including Jerusalem, Bethlehem, Gaza, and Nablus.
[4] The terms of the treaty provoked outcries and consternation throughout the Arab world, and Muslim imams denounced Ismail because of the loss of Jerusalem.
