Who "found" this? Most Indian myths are based on real people/incidents with some added embroidery. I would bet that most Greek myths are also likewise based on real people or incidents As to Khalid Ibn Walid, like I said wotzisname has several details and sources in his works - as for coinage, I don't agree that having the archangel Michael on a coin is evidence that he may have existed. And if that can be said of Archangel Michael it can apply to Aristotle and Caesar and Jesus. So yeah, I reject your assumptions. I'm not particularly interested in Khalid Ibn Walid, he was only one general out of several hundred, the fact that many people spoke about him may have as much to do with his personality as his actions. There are others who wax poetic about Umar [one Egyptian told me he was a ten feet tall Negro who never lost a battle] - the way I see it, people are identified by their actions and consequences not vice versa. So yeah, maybe Aristotle existed, maybe not - Jesus has a bigger following and more literature about him and yet we can't say if he was who everyone says he was. So maybe there were no Greek philosophers. Maybe the Romans are a myth. Maybe the Byzantine empire was a small city by today's standards. The point is, all history is maybes. The only reality really is what you consider applicable today. So you reject Khalid or Mohammed and I reject all the Greek Philosophers and the Romans and it makes no difference to what they achieved - even if you decide unilaterally that there was no Mohammed or Khalid, there is still the Arabic conquest from Yemen to Spain. There is still Islam.
