Sadi and his Envious Class-friend
A fellow-student at Nezamiah displayed malevolence towards me, and I informed my tutor, saying: “Whenever I give more proper answers than he the envious fellow becomes offended.”
The professor replied: “The envy of thy friend is not agreeable to thee, but I know not who told thee that back-biting was commendable. If he seek perdition through the path of envy, thou wilt join him by the path of slander.”
