 Upon his return to Yogyakarta , Darwis ( now played by Lukman Sardi ) changes his name to Ahmad Dahlan and begins teaching Islam , preaching that prayers need only come from inner peace and do not require large donations or sacrifices . Conflict soon arises between Dahlan and the local <unk> ( religious leaders ) after he shows that the direction in which they pray is wrong , pointing not to the Kaaba in Mecca but to Africa . The <unk> , especially <unk> Kamaludiningrat ( <unk> Rahardjo ) , <unk> Dahlan as the leader of a cult and provoke a crowd of their followers to destroy the building next to Dahlan 's house used for studying prayer .
