When thou seest thine enemy in trouble, curl not thy whiskers in contempt; for in every bone there is marrow, and within every jacket there is a man.
SaadiA friend whom you have been gaining during your whole life, you ought not to be displeased with in a moment. A stone is many years becoming a ruby - take care that you do not destroy it in an instant against another stone.
SaadiA dog will never forget the crumb thou gavest him, though thou mayst afterwards throw a hundred stones at his head.
Saadi
