Imam Sadiq (a.s) said: “God the Almighty revealed to David. Why are you so quiet?” David said: “Your awe has silenced me.” God asked: “Why are you so slim?” He said: “Your love made me slim.” God the Almighty said: “Why are you so poor?” He said: “Standing up for your right has made me poor.” God the Almighty said: “O' David! Why have you humiliated yourself?” He said: “Your indescribable Majesty and Grandeur has humiliated me.” God the Almighty said: “O' David! Now I give you the glad tidings that you will receive what you love the Day you meet Me. Associate with the people according to their own ways, but be separate from them in your religious issues. You will attain whatever you want from Me on the Resurrection Day.”
