It makes it a little difficult for us Kafirs to figure out: “Does he want me to do something, or does he want to kill me?”
The words are the same either way. It makes taking them seriously pretty tough. If everything is a life-or-death struggle, then nothing is a life-or-death struggle.
Our first clue about the dualism is in the Koran, which is actually two books, the Koran of Mecca (early) and the Koran of Medina (later). The insight into the logic of the Koran comes from the large numbers of contradictions in it. On the surface, Islam resolves these contradictions by resorting to abrogation. This means that the verse written later supersedes the earlier verse. But in fact, since the Koran is considered by Muslims to be the perfect word of Allah, both verses are sacred and true. The later verse is better, but the earlier verse cannot be wrong since Allah is perfect. This is the foundation of dualism. Both verses are right. Both sides of the contradiction are true in dualistic logic. The circumstances govern which verse is used.
