1.  Imam Ja’far Sadiq (a.s.) narrates from his predecessors that Amirul Momineen (a.s.) said, “It is the habit of jurists and wise people to advise about three things in their every letter written  to  each  other.  Nothing  else  was  present  among them; that is one who is only worried about the hereafter, Allah  will  fulfill  his  worldly  wishes  and  needs.  Allah improves the exterior of one who improves his interior and one who develops good between himself and Allah, Allah develops good between him and the people.”
