“On one of the occasion of my meeting with abu Ja‘far (a.s.) when I went tosee him he asked me to wait until the sun became very hot on me. I tried to follow the shadow from the sun. No very long thereafter a people came out of his presence that looked like locusts dressed in large gowns and very oale and slim due to extensive worshipping. Their beautiful scene made me to forget other things. When I went in the presence of the Imam (a.s.) he said, “I am afraid I caused you hardships.” I said, “Yes, it was difficult but, by Allah, I forgot other things when I saw them. A people passed by the like of whose beauty I had not seen before. They looked like locusts and pale and slim due to worshipping a great deal.” The Imam (a.s.) said, “O Sa‘d , did you see them?” I said, “Yes, I saw them.” The Imam (a.s.) said, “They are your brethren from Jinns.” The narrator has said that he asked The Imam (a.s.), “Do they come to you?” He said, “Yes, they come to us for religious instructions and to learn the lawful and unlawful matters.”
