I also read a very apologetic biography of Muhammad, and then several other accounts of his life
The trouble with these accounts is that they postdate Muhammad (pbuh) by quite a few years..
These books really trouble me.
Some of the things they contain really trouble me too.
It seems to me that the most natural reading of the Quran is that it's a war manual for Muslims against the rest of humanity.
If you read all of the Qur'aan the whole way through, and take all of it together, and understand the context both of individual verses and of the Qur'aan as a whole, you may learn to see it in a different light. The Qur'aan was revealed at a time when society in that part of the world was violent and misogynistic and generally not a nice society to be living in. Against that backdrop, the Qur'aan was a vast improvement, a practical way to reform that society. But I don't believe it is a blueprint for all time. If you see it in this light, as a text which combines some universal teachings with quite a few teachings, and a way of framing reality, applicable to the needs of that time and place, which it would be plainly inappropriate (to say the least!) to apply in most parts of the world today, then you might start to get a different measure for the Qur'aan and what it is (and what it is not). So many Muslims do see it as a blueprint for all eternity. Doesn't mean they're right. In his last sermon to the people before he died, Muhammad (pbuh) beseeched Allaah, saying that he hoped that the
last to hear his message would understand it better than those gathered before him that day.
But I do believe that there is a war going on, not between Muslims and non-Muslims mind you, but between the forces of the light and the forces of darkness. And there are people who call themselves Muslims on both sides (as there are people who call themselves the adherents of other traditions), which makes it all a bit messy and complicated. But this belief of mine, which is as much a Gnostic one as anything, doesn't mean that I use the Qur'aan as a war manual. I have my own war manual (that I put together myself) for this spiritual war.
I'm not the first to notice that ISIS's interpretation of Islamic scripture is very natural and extremely defensible.
Not so. Their interpretation is an abusive and far more intolerant and violent one more in keeping with the society that the Qur'aan was aimed at reforming.
It really seems as though the scripture is a huge negative influence on humanity
Of course, we don't know how much better or worse humanity might have been without it.
I'm inclined to take you at your word, and my only conclusion is that you have the world view you have in spite of the scripture, not because of it.
Well, the path I tread and the beliefs I hold started way before I converted to Islaam, and they have continued to evolve since within that framework I outlined to you earlier. Moreover, you seem to place too much stock on the scripture, which is important to be sure, but just one part of a Muslim's spiritual and religious life. Or at least this Muslim's spiritual and religious life.
