That was Vinods comment.
Found this in another forum... contains some useful information
Hello there, do you guys know any book that cover the whole period of Khalifa Umer, his period is the golden era of Islam.
Though you should always treat the works of Orientalists with some caution, I generally find two historical narratives quite useful:
1. Albert Hourani's "History of the Arab Peoples"
2. Bernard Lewis' "Arabs in History"
If you can, you might also want to try the rare "The Jews of Islam", also by Bernard Lewis.
The Amman Message
reclaim your religion from extremists
Nine things the Lord has commanded me: Fear of God in private and in public; Justness, whether in anger or in calmness; Moderation in both poverty and affluence; That I should join hands with those who break away from me; And give to those who deprive me; And forgive those who wrong me; And that my silence should be meditation; And my words remembrance of God; And my vision keen observation.- Prophet Muhammad (pbuh)
The Hadiths are the only place to get unbiased info on the history of Islam. It sounds like it wouldn't be unbiased given that they are Islamic books written by some of the first and earliest Muslims, but the fact that Muslims reject many of the Hadiths as being fabrications because they describe many truths about Islam and Muhammad that Muslims now reject, causes me to consider it to be accurate.
