One case of supporting morality in the shadow of mysticism can be seen in the books of chivalrousness in which the place of morality in professional teaching has been made clear. The books are those written by the great chivalrous men in which they taught their followers how to be chivalrous when teaching professions. As is understood, one should become chivalrous before taking a profession. That is, chivalrous with all its essential ethical properties needed to attain such an important place. In the paper, the terminology of the subject and its cases of use in the Quran has been considered. Again, the background of study with regard to the prophets has been referred to and the relationship between professional classes and chivalrousness has been explained. And finally, particular approach of those of chivalrousness to morality when practicing professions has been justified.
