I too, have read the Qur'an a number of times, in both English and Arabic, and have a couple of counters to that rather offensive and bigoted quote. First, the Qur'an, unlike the Bible, is not a narrative expected to promote morality through example. It is considered the living, breathing, actual word of God, dictated and preserved to inspire and educate through spirit and meaning. If you approach it with the typical 21st century American (Judaeo-) Christian idea of biblical narrative, then yes, you will come away disappointed, puzzled, and probably very misinformed. If you approach it as you would the ecstatic poetry of say, Julian of Norwich, or Hildegard of Bingen, you may see things differently.

Second, it's pretty clear that poetic meaning is lost on Mr. Harris, if he thinks that chapters like The Spider (al-Ankabut, su.29), or The Light (al-Nur, su.24), or The Women (al-Nisa', su.4), The Dawn (al-Fajr, su.89), or The Clot (al-Alaq, su.96) are without value. Finally, if the Qur'an is any worse than the Holy Bible as a moral compass, I'll eat my shorts.

How about Surah 2 verse 256?  "Let there be no compulsion in religion."

A simple Google search for peaceful quotations from the Quran turns up plenty of positive wisdom, such as: "Whoever recommends and helps a good cause becomes a partner therein, and whoever recommends and helps an evil cause shares in its burdens" Qur’an:4:85

I won't say that the Quran is a particularly "wise" book, but the idea that everything but a few lines about patience and generosity is "just vilification of the infidel" is patently unfair.  Sura 2 (the Cow), verse 62, in the Yusuf Ali translation: "Those who believe (in the Qur'an)  and those who follow the Jewish (scriptures), and the Christians and the Sabians, - any who believe in Allah and the Last Day, and work righteousness, shall have their reward with the Lord; on them shall be no fear, nor shall they grieve." 1,400 years ago, the Qur'an was preaching salvation of followers of other faiths, an idea which only became widespread among Christians less than a century ago.  A shame so many Muslims don't bother to pay attention to this verse.

Why is the Koran a good book? I'll give two examples why.
