Rather than commandments there are The "Five Pillars of Islam" and "The 6 Articles of Faith"
But to get those you first need to talk to Thor in Nordia Village. He'll give you the quest to gather 6 Golden Calfs by slaying Elder Pigs and rewards you with the repair hammer. Bring the hammer to Poseidon in Atlantis City, and he'll fix the five broken pillars for you. As for the Articles of Faith; find Flying-with-birds south of Bison Plains if you reach lvl 20, help him defeat the firedragon sieges and his reward will be the Articles of Faith.
