1.  Imam Ja’far Sadiq  narrates from his ancestors that the  Holy  Prophet  (s.a.w.s.)  was  asked,  “What  will  have salvation  on  the  Day  of  Judgment?”  The  Holy  Prophet (s.a.w.s.) replied, “Salvation is only and only in not cheating Allah so that He also doesn’t cheat you. Surely Allah cheats a person who cheats Him and takes faith away from him. A person should know that he has cheated himself.” The Holy Prophet  (s.a.w.s.)  was  asked,  “How  does  a  person  cheat Allah?” He answered, “By obeying the order of Allah but for the sake of someone else. Keep away from showoff because it is polytheism. Surely, a person who does showoff will be called  with  four  names  on  the  Day  of  Judgment  viz.  O disbeliever, O mischief-monger, O cunning, O loser! Your deeds are wasted. Your reward was reduced continuously and there is nothing left for you today. Go and ask for the reward from one for whom you performed good deeds.”
