Umar Ibn Al Khattaab gave the following advice to Ahnaf who he had employed as a governor, advice that is applicable to all of us:
O Ahnaf, one who laughs too much loses dignity; one who jokes too much loses respect; whoever does something a great deal, becomes known for it; one who speaks a great deal makes mistakes; one who makes many mistakes loses his sense of dignity. Whoever loses his sense of dignity loses his fear of God and whoever loses his fear of God is spiritually dead.
