How could anyone possibly believe he was sent by God? How can anyone see Islam as a religion of peace? The Prophet was nearly continuously involved in warfare.
The Mohammedan temper was not tolerant. It was, on the
contrary, fanatical and bloodthirsty. It felt no respect for, nor even
curiosity about, those from whom it differed. It was absurdly vain of
itself, regarding with contempt the high Christian culture about it. It
still so regards it even today. - Hilaire Belloc
