Thomas Carlyle, the Scottish historian wrote about the Prophet Muhammad (pbuh). Excerpt from “Lectures on Heroes”, p. 66.
“They called him Prophet, you say? Why, he stood there face to face with them; bare, not enshrined in any mystery, visibly clouting his own cloak, cobbling his own shoes, fighting, counselling, ordering in the midst of them, they must have seen what kind of a man he was, let him be called what you like! No emperor with his tiaras was obeyed as this man in a cloak of his own clouting. During three and twenty years of rough actual trial, I find something of a veritable Hero necessary for that of itself.”
