Saladin gave three reasons for retaking Jerusalem in his speech: 1) Jerusalem had been controlled by enemies for 91 years, preventing worship of God there, 2) the devotion of Muslim rulers to retake it had weakened over time, and 3) God had chosen Saladin's family to unite hearts in recovering it. He argued this would make Muslims fortunate and inspire devotion if successful. Muslims likely listened because of religious devotion to Jerusalem and Saladin's reputation/family.
