A Sh'ia scholar states: Some historians claim that Umar was a most awe-inspiring man, and when he accepted Islam, the idolaters were gripped with fear for their lives. But this is only a case of a dominant myth being in conflict with ugly facts. When Umar accepted Islam, the idolaters remained where they were, and nothing changed for them; but it was Muhammad who was compelled to leave his home, and had to find sanctuary in a desolate ravine.
