The Crusader aggression against the Arab region is one of the events of Arab and Islamic history, and the issue of prisoners, whether with Muslims or with the Crusaders, was among the important issues that emerged during that aggression because of its humanitarian or aggressive aspects related to the treatment they received from both sides. Others were ill-treated, in a way that amounted to sale in the slave market, and even to death, the thing that reflects the ethics and principles of those in charge of families. It is worth noting that the Arab Muslims in general have morals in dealings with the prisoners, based on the principles of the tolerant Islamic religion.
