Zora s Revert Zora please explain why you have reverted my contribution to the How do we know about Muhammad section It is a simple fact that after reading the Qur an and the all of the hadiths you will not have a coherent picture of who Muhammad was or what he did i e his biography That information was collected in the sirah Why are you reverting edits without any explanation Have you really studied the sirah 3 July 2005 22 37 UTC
