Yep, the Koran like the Bible has two main story lines. But, unlike the Bible there are other books, Hadith, Ishaq, etc. So, the early verses, up to about 5 are very nice and loving in Koran. But, then it shows the other side, and by the time you get to # 8 you get this horror show, rearing it's head. The Dominion part.
Islam itself very soon split into 2 schisms, Sunni and Sh'ia, over who was anointed to lead after MoMo and just what the horror show should be. But, that was no Reformation. Their Prototype of course, was the Horror Show we call the Early Christians.
And in these other books, are the reports of those around him of what Mohammed did and said to them, in a civics sense.
He said at one point he would cut off the hand of his own sister, if she sinned before Allah.
