In accordance with this order, enormous sums were paid back out of the state treasury, and the Christians called down blessings on the heads of the Muslims, saying, "May God give you rule over us again and make you victorious over the Romans; had it been they, they would not have given us back anything, but would have taken all that remained with us." Similarly, during the time of the Crusades, Saladin returned the jizya to the Christians of Syria when he was compelled to retract from it. Moreover, the Christian tribe of al-Jurajima, in the neighborhood of Antioch, made peace with the Muslims, promising to be their allies and fight on their side in battle, on condition that they should not be called upon to pay jizya and should receive their proper share of the booty. The orientalist Thomas Walker Arnold writes that even Muslims were made to pay a tax if they were exempted from military service, like non-Muslims. Thus, the Shafi'i scholar al-Khaṭīb ash-Shirbīniy states: "Military service is not obligatory for non-Muslims – especially for dhimmis since they give jizya so that we protect and defend them, and not so that he defends us." Ibn Hajar al-Asqalani states that there is a consensus amongst Islamic jurists that jizya is in exchange for military service. In the case of war, jizya is seen as an option to end hostilities. According to Abu Kalam Azad, one of the main objectives of jizya was to facilitate a peaceful solution to hostility, since non-Muslims who engaged in fighting against Muslims were thereby given the option of making peace by agreeing to pay jizya. In this sense, jizya is seen as a means by which to legalize the cessation of war and military conflict with non-Muslims. In a similar vein, Mahmud Shaltut states that "jizya was never intended as payment in return for one's life or retaining one's religion, it was intended as a symbol to signify yielding, an end of hostility and a participation in shouldering the burdens of the state."
