A 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.
SaadiWhosoever formeth an intimacy with the enemies of his friends, does so to injure the latter. O wise man! wash your hands of that friend who associates with your enemies.
SaadiThat sorrow which is the harbinger of joy is preferable to the joy which is followed by sorrow.
