“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.”
