It was narrated by Abu Ja‘far Muhammad ibn Ali ibn Babawayh, may Allah سبحانه وتعالى have mercy on him. He (Ibn Babawayn) said Muhammad ibn al-Hasan ibn al-Walid informed us from Muhammad ibn al-Hasan al-Saffar from al-‘Abbas ibn Ma‘ruf from Sa‘dan ibn Muslim from Jahm ibn Abi Jahm, who said: I saw Abu al-Hasan Musa ibn Ja‘far عليه السلام, peace be upon them both, and He عليه السلام had prostrated after the three rak‘ahs of Maghrib. So I (narrator) said to Him عليه السلام: “May I be your ransom, I saw you prostrating after the three.” Imam عليه السلام said: “And you saw me?” I said: “Yes.” Imam عليه السلام said: “Then do not abandon it, for supplication in it is answered.”
