3. Ahmad ibn Idris and Muhammad ibn Yahya have narrated from al-Hassan ibn Ali al-Kufiy from ibn al-Faddal from certain person of our people from Sa‘d al-Askaf who has said the following. “Once I to ask permission to meet abu Ja‘far (a.s.). I found saddles of camels lined up in front of the door and noises coming very loud and then a people came out with turbans like those of the Indian gypsies. I asked abu Ja‘far (a.s.) about them and said, may Allah take my soul in service for your cause. Today it took a long time to receive permission to meet you. I saw a people coming out with turbans whom I could not recognize.” He said, “Do you know, O Sa‘d, who they are?” I said, “No, I do not know.” The Imam (a.s.) said, “They were your brethren in religion from Jinns. They come to us for religious instructions, to learn the lawful and unlawful matters and the principles of their religion.”

4. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Ibrahim ibn abu al-Balad from Sadir al-Sayrafi who has said the following. “Abu Ja‘far (a.s.) asked me to help him in a few things in Maina. I left and when reached fajj al-Rawha’ a man waved to me with his cloths. The narrator has said that I turned to him and I though he was thirsty. I offered the cup but he declined saying, “I do not need it.” He gave a letter with its ink still not dried up. The narrator has said that when looked at it, it had the seal of abu Ja‘far (a.s.) on. I asked him when were you in the presence of abu Ja‘far (a.s.)?” He said, “Just now I was in his presence.” In the letter there were few things that he had commanded me to do. When looked around there was no one with me.” The narrator has said that then I went to meet abu Ja‘far (a.s.) and said, may Allah take my soul in service for your cause, a man came to me with your letter the ink of which was not yet dried up.” He said, “O Sadir, we servants from Jinns. When we would need a thing to happen quickly we send them to do it.”

I then asked him, “My master, who are you talking to?” He said, “This is ‘Amir al-Zahra’i. He has come to ask a few questions and he has certain complains.” I then asked, “My master, I like to hear his words.” He said, “If you would hear his words you will have fever for one year.” I said, “My master, I like to hear him.” He said, “All right, then listen.” I listened and I heard something like a whistle. I then felt fever for one year.”
