Was I surprised when Imam Ghazali once again immpressed and inspried me with his writing? Well, yeah, actually I was. This was a really good book, Imam Ghazali comes at the whole issue from points of view I didn't quite have in mind when I picked the book up.
Adab un-Nikah explains many aspects of marriage that never made sense to me. The book goes over the advantages of marriage, the disadvantages, the problem with woman (And he gets picky) and then finally Imam Ghazali's conclusion. He hits on many arcane ideas and concepts that were new to me. A lot of chapters covered things I'd never related to marriage.
The book is written specifically for men, but woman will find this book useful also (If only to glean the wisom in Imam Ghazali's written word). My only difficulty in the book was that it was written from a very high-level sufi perspective. Many of examples used in the book do not exist anymore, or are very uncommon. (ie. topics covering single men who have devoted their entire lives to Dhikr)
The prose is easy...the layman can easily understand the text. At some parts, I wonder at how accurate the translation was; but alas, this is the only English version available.
I recommend this book for all married muslims, esspecially the men. Unmarried men/woman might be confused at some aspects of the book, but it's still good to read. As for non-muslims...You'll need a strong Islamic Knowledge base before you try tackling this one...
