I'm not a fan. I was expecting a critical analysis, but it's mostly a perfect personal interpretation, that makes the Qur'an and Islam the perfect basis for everything ever, where everything is perfect in every imaginable way. In a way that is what Muslims might believe, so in that light it was insightful, but it wasn't what I hoped for when looking at the book.
There are no difficulties in anything, no contradicting verses get mentioned (the ''everyone gets dark eyed virgins'' part of paradise are now all spouses made virgin again, for whatever reason, ''nobody gets mentioned by name or personally isn't being discussed in the light of Sura 111: 'May the hands of Abu Laheb be ruined! May he be ruined too! Neither his wealth nor his gains will help him: he will burn in the Flaming Fire -- and so will his wife, the firewood carrier, with a palm-fibre rope around her neck.'), no orthodox scholars get mentioned, no inter-Islamic ideologies get mentioned, no actual state policies or circumstances get mentioned. Islam is perfectly compatible with everything modern, even though there are tons of people out there violently protesting against it, women are perfectly equal, etc. It's beyond apologetic, it's a utopia with no basis in reality. It's the same old story of ''only defensive wars'' (during the life of the Prophet, perhaps) without explaining how Muslims ''defended'' themselves all the way into Al-Andalus, even under the ''rightly guided caliphs''. I don't even condemn it, I just want to understand the justifications and how the religion is seen to be compatible with it. I understand this isn't a history book, but you can't ''understand'' anything if you don't allow at least a small insight into the reality of the religion and its manifestations.
I've read Haleem's translation of the Qur'an, and that also plays a massive part in this work. A vast section of every chapter is used for semantic debate and translation errors of previous translators, which are really only insightful if you've read these other translations.
All in all, I'm perfectly aware of the fact that Mr. Haleem is far more qualified on every word in the Qur'an than I am, and that his opinion on it carries infinitely more weight, but it's just that when I read ''Understanding the Qur'an'' I didn't expect this much ''How I understand the Qur'an''. I suppose I'll go read Ibn Taymiyyah myself to see where all these beautifully peaceful messages seem to get so distorted.
Basically, it's a short read, but I still don't think it's worth the time. Read the Qur'an, read the Hadith, talk to Muslims, and most of it should be pretty clear to you.
