 The Maturidis say that the unaided human mind is able to find out that some of the more major sins such as alcohol or murder are evil without the help of revelation, but still maintain that revelation is the ultimate source of knowledge.Additionally, the Maturidi believe that God created and can control all of His creation, but that he allows humans to make individual decisions and choices for themselves.Jahmis were the followers of the Islamic theologian Jahm bin Safwan who associate himself with Al-Harith ibn Surayj.
