I have managed to read the greater part of the Qur'an, tedious though it is. The bulk of it is taken up with many, many repetitions of a few ideas: 1. God is all-powerful and all-knowing and there's only one of him--and you can't fudge this principle by having this singular being appear in different manifestations, for example, as his own son ( although you'd think that, being omnipotent, he could if he wanted to). 2. The Qur'an is the record of God speaking through Mohammed. 3. If you believe 1 & 2 and do a few things attendant on that belief you will be rewarded in the afterlife and if you don't, you will be punished horribly. Actually, the threatening-horrible-punishment theme is a very large part of the the Qur'an. Now, it is true that there is the occasional pleasant-sounding bit, like the one about there being no compulsion in religion, but these are generally quite isolated islets in the sea of numbers 1, 2, and 3. They could be compiled into a little pamphlet of 3 or 4 pages. And if you read closely, it turns out that most of the nice bits can be construed to apply to only other Muslims.
