This is another excerpt from Bill Warner’s book Abridged Koran where the verses of Koran are arranged in their chronological order and provided with facts from prophet Muhammad’s life, giving context for them. The last chapter, Conclusions, doesn’t contain any more Koran verses, but this is interesting and useful material.
The constant theme of Islam’s perfect, eternal, and universal Koran is the division between those who believe Mohammed, and those who don’t. This sacred division is dualism; Kafirs are not fully human and fall under a separate moral code. The dualistic separation is in politics, culture and religion. This duality is carried further by two different approaches to the Kafir in the Koran of Mecca and the Koran of Medina.
Some verses of the Koran contradict each other, but the text states a principle for resolving the contradictions. The later verse abrogates (nullifies) the earlier verse. However, since the entire Koran comes from Allah, then all verses are true, and no verse is actually false. The later, contradictory verse is merely stronger than the earlier, weaker verse. In practice, both sides of a contradiction can be true — logical duality.
