5. A number of our people have narrated from Sahl ibn Ziyad, who has narrated from more than one person from al-Husayn ibn al-Hassan. All of the above have narrated from Muhammad ibn ‘Uwarma from Muhammad ibn Ali from ‘Isma’il ibn Yasar from ‘Uthman ibn Yusuf who has said that, reported to him ‘Abd Allah ibn Kaysan, from Abu ‘Abdillah عليه السلام who has said the following: “Once I said to the Imam, ‘May Allah keep my soul in service for your cause, I am your servant, abu ‘Abd Allah ibn Kaysan.’ The Imam said, ‘I know your genealogy. However, I do not know you (so well).’ I said, ‘I was born in the mountains and grew up in the land of Persia. I associate with people in business and other occasions. I, thus, associate with a man and find his appearance very good, to be of good manners and more trustworthy. When I investigate, I find him to be one of your enemies. I also associate with another man who has bad manners, is less trustworthy and hot tempered. I then investigate and find him to be of your supporters and followers. Why is it so?’ “He (the Imam) said, ‘O ibn Kaysan, Allah, the Majestic, the Glorious, took a clay from paradise and also from fire and then mixed them together. Then He separated this from that and that from this. The good appearances, good manners and trustworthiness that you find in them (our enemies) is because of the touch of the clay from paradise but they will return to that from which they are made. The deceitfulness, bad manners and hot-temperament that you find in them (our supporters and followers) is because of the touch of the clay from fire, however, they will return to that from which they were made.’”
