Man is, beyond dispute, the most excellent of created beings, and the vilest animal is a dog; but the sages agree that a grateful dog is better than an ungrateful man.
SaadiWhen you see contention amongst your enemies, go and sit at ease with your friends; but when you see them of one mind, string your bow, and place stones upon the ramparts.
SaadiNo one ever sowed the grain of generosity who gathered not up the harvest of the desire of his heart.
