The historian Thomas Carlyle considered Muhammad one of the world's greatest heroes, yet even he called the Koran "as toilsome reading as I ever undertook; a wearisome, confused jumble."
Historikeren Thomas Carlyle anså Muhammed for en af verdens største helte, men selv han kaldte Koranen "det besværligste læsning, jeg nogensinde har gjort, en trættende, forvirrende gang roderi."
