A number of our people have narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from al-Muthanna al-Hannat from abu Basir who has said the following.
"Once I went to see Abu Ja‘far (as) and asked him, "Are you the heirs of the Messenger of Allah?" He said, "Yes, we are his heirs." I then asked, "Was the Messenger of Allah the heir of the prophets and knew all that they knew?" He said to me, "Yes, it is true." I then asked, "Do you have the power to bring the dead back to life and cure the lepers, and the blind?" He said, "Yes, we do have such powers by the permission of Allah." Then he said to me, "Come closer to me, O Abu Muhammad." I went closer to him and he rubbed my face and my eyes and I saw the sun, the skies, the earth, the houses and all things in the town. Then he said to me, "Do you like to live this way and will have what others have and be responsible for whatever they will be held responsible on the Day of Judgment or like to live as before and will have paradise purely?" I said, "I would like to live as I lived before." He rubbed my eyes and I found myself as before."
The narrator has said that he told it to ibn abu ‘Umayr who said, "I testify that this is true just as the day is true."
