Origin has three chapters except the origin of power, which has two specific chapters, but the third chapter was dropped from it because His power is restricted and not absolute, which is the saying of the scholars, and what He did not will to happen is that if He had willed it to be, it would have been how it would have been, so His being was suspended, so He refrained from the influence of power over it for another reason. He did not have influence, and this is a vague subject that will never be opened.
