The Just sultan and hero, who defeated the Crusaders in the battle of Hittin, and drove them out of Jerusalem. Salahud-Din al-Ayyubiyy ordered the matters of the Rightcreed, according to the methodology of Imam al-Ash^ariyy to be recited on the top of the minarets every morning after the call (adhan) for the Subh prayer. Ibnu Hibah al-Makkiyy, a famous Ash^ariyy scholar, authored a book pertaining to the creed--in poetry--which he presented as a gift to Salahud-Din al-Ayyubiyy. Salahud-Din al-Ayyubiyy ordered this book taught to the children in the schools. Despite the fact Salahud-Din al-Ayyubiyy was so occupied with fighting the battles he was renowned to have fought, he took the time each day to teach his small children from a book of the ^Aqidah. He used to ask his children to recite before him what they had memorized from this book--even though he would be in the front lines, preparing for the battle-- --to ensure they held the proper creed.
