The document compares Catholicism and Islam in terms of church, prayer, and traditions. It notes that mosques must have minarets and domes and be sparsely decorated inside, while churches have altars in the center and are decorated. It also notes that Catholics pray with the Bible or rosary to God once a week in services, while Muslims pray with the Koran to Allah several times a day after washing. Both religions' holy books are the Bible and Koran respectively, and they differ in traditions like touching holy water before church versus washing before prayer in mosques.
