According to their [Muslims’] doctrine, whatever is stolen or plundered from others of a different faith, is properly taken, and the theft is no crime; whilst those who suffer death or injury by the hands of Christians, are considered as martyrs. If, therefore, they were not prohibited and restrained by the [Mongol] powers who now govern them, they would commit many outrages. These principles are common to all Saracens.
— Marco Polo
