1. [1/-] al-Kafi: Ali b. Ibrahim from Muhammad b. Isa from Musa b. al-Qasim al-Bajali from Ali b. Ja’far who said: Muhammad b. Ismail [b. Ja’far] approached me when we were in Makka and had just completed the Umra in the month of Rajab – he said: O uncle, I want to travel to Baghdad but first I wish to bid farewell to my uncle Aba al-Hasan – that is Musa b. Ja’far. I would like it if you accompany me to meet him. I came out with him heading towards my brother who was in his house in Huba. We reached a little after Maghrib. I knocked the door and was answered by my brother who said: who is that? I said: Ali, he said: I am just coming – he was someone who took long in making the ablution – so I said: make haste, he said: I will. Eventually he came out wearing a lower garment [waist-wrapper] dyed in an earthish hue, knotted at his neck and proceeded to sit at the threshold [step] of the door. Ali b. Ja’far said: I bent towards him, kissed his forehead and said: I have come to you concerning a matter, if you find it to be appropriate then it is Allah who facilitated it, and if it is not [if you find it disagreeable] then how often do we err [as humans]. He said: what is it? I said: this is the son of your brother, he wishes to bid you farewell and depart towards Baghdad. He [the Imam] said to me: call him [Muhammad b. Ismail]. I called him and he was close by. He [Muhammad b. Ismail] came near him, kissed his forehead and said: May I be made your ransom, advise me, he [the Imam] said: I advise you to fear Allah concerning my blood, he replied to him: May Allah do such to whoever wishes ill for you, and he began supplicating against the one who harbors ill-feeling towards him. Then he kissed his forehead a second time and said: O uncle, advise me, he said: I advise you to fear Allah concerning my blood, he said: May Allah do such and such to whoever wishes ill for you [and He has already done so]. Then he kissed his forehead a third time and said: O uncle, advise me, he said: I advise you to fear Allah concerning my blood, so he supplicated against the one who wishes ill towards him, then he turned away from him [to depart], I too began walking away with him, but my brother said to me: O Ali, [stop] where you are. I halted, he called me and I entered [the house]. He outstretched a pouch which contained a hundred gold coins and handed it to me and said: tell the son of your brother [nephew] to make use of it on his journey. Ali said: I took it and twisted it around the hem of my cloak, then he handed me another hundred and said: give it to him, then he handed me another pouch and said: give it to him also. I said: may I be made your ransom, if you fear him doing what you described then why are you aiding him against yourself [by helping him]? he said: If I maintain my ties with him and he cuts me off then Allah will cut off his life-time. Then he took to hand a tanned leather pillow [hollowed out to store money] in which were three thousand fine silver coins and said: give this to him as well. He [Ali b. Ja’far] said: I came out and gave him the first hundred whereupon he became extremely delighted and supplicated for his uncle, then I gave him the second and the third. He became so happy that I thought he will turn back and not depart [for Baghdad]. Lastly I gave him the three thousand silver coins. Nevertheless, he departed on his mission until he went in to see Harun [the Abbasid Caliph] and greeted him by acknowledging his Caliphate [said: peace be upon you O Commander of the Faithful]. Then he said: I never thought that there could be two Caliphs on earth [at the same time] until I saw my uncle Musa b. Ja’far being greeted with the Caliphate [people referring to him as the Caliph when greeting him]. Harun sent him one hundred thousand silver coins [as a reward for his reporting about his uncle] but Allah afflicted him [Muhammad b. Ismail] with an ailment [in which an ulcer grows and chokes the passage in the throat] and he did not get the chance to even take a look at a single silver coin [that he had been gifted] let alone touch it.
