What reasons does Saladin give for retaking Jerusalem what arguments does he use to inspire his listeners?

Saladin's primary reason for retaking Jerusalem was to fulfill his religious duty to defend the Holy Land from Christian invaders. He also used the argument that the city rightfully belonged to the Muslims as it had been under their control prior to the Crusades. Saladin inspired his listeners by emphasizing the importance of unity, the virtues of jihad, and the potential rewards in both this world and the next for those who fought to liberate the city.
