Whosoever 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.
SaadiIf thou art of elephant-strength or of lion-claw, still peace is, in my opinion, better than strife.
SaadiThe wise man tells not what he knows. It is not prudent to sport with one's head by revealing the king's secrets.
SaadiReveal not every secret you have to a friend, for how can you tell but that friend may hereafter become and enemy. And bring not all mischief you are able to upon an enemy, for he may one day become your friend.
Saadi
