being a muslim i have the right to say , the book is incredible but a big mistake which i want to be corrected is that in chapter 9 persistence there is a topic 'the last great prophet' reviewed by thomas sugrue in that the information given about khadijah ra is wrong. yes it is correct that khadijah ra was 40 yrs old buisness women and mohammed s.a.w was 25 yrs old when they got married but the mistake is ,it is given that muhammed s.a.w was 28 yrs old and the info given about how khadijah and muhammed s.a.w got married is wrong .totally wrong.it is given that 'her father [khadijah's father]would have objected to such marriage [muhammed s.a.w and khadijah ra's marriage] ,so she got him [khadijah's father] drunk and held him up while he gave the paternal blessing' . it never happened like that . khadijah ra never made his dad drunk . so please i urge you and request to correct it coz because of these issues it will be difficult for us to appreciate and trust the words of the author of book and the people who don't know about this will believe the false information . thank you and pls correct it
