They also say Moses, Abraham, and in fact Adam, were Muslims. They do not see Mohammad as starting a new religion, but as more of a Reformation figure, trying to turn people back to fidelity to the true religion which existed from the Creation of Man.
I Think Abraham may have given birth to islam thrugh the slave women named Hagar.... God said "I will make a nation also unto Ishmael but my covenant shall be with Isaac"... Abraham's other son through his wife Sarah.. Isaac being the blood line of Gods chosen people.... Ishmael being otherwise..... (mho)
