خير تعمل شر تلقى
Kharen te’mel sharren telqa
Translation: The good you do is rewarded with evil.
Meaning: No good deed will go unpunished. Those whom you help will either take you for a sucker, or go into further trouble and manage to drag you along. Play it safe, don’t be good, or at least don’t let anyone know that.
