Hadith.968 - Jahm ibn Abi Jahm narrated that he saw Imam Musa ibn Ja'far (as) performing a prostration after the three rak'ahs of Maghrib prayer. He said: "May I be your ransom! I saw you prostrate after the three [rak'ahs]." Imam (as) replied: "And you observed me doing that?" Jahm said: "Yes." The Imam (as) then said: "Do not abandon it, for the supplication made during it is answered."
