This is a beautifully written book with lots of insight and explanations of the historical background to the life of the Prophet. The book is deeply moving and written with a humble charm that is very refreshing.
My only criticism is that, certainly in the earlier parts, the book jumps backwards and forwards from various life events. This is absolutely fine if you've read other books on the life of the Prophet beforehand and know the sequence of events, otherwise it can be a tad confusing.
Overall well worth reading, a truly scholarly work which one would expect from Tariq Ramadan.
