1. al-Husayn ibn Muhammad al-Ash‘ari has narrated from Mu‘alla ibn Muhammad from Ali ibn al-Sindi al-Qummi who has said that narrated to us ‘Isa ibn ‘Abd al-Rahman from his father the following. “Once ibn al-‘Ukkasha ibn Muhsin al-Asadi went to see abu Ja‘far and abu ‘Abdallah عليه السلام was present with him. Grapes were offered to him. The Imam عليه السلام said, “The old man and the small boy eat grasps one piece at a time and one who is anxious for filling himself up eats several pieces at a time but you should take two pieces at a time because it is mustahab (preferable) to do so.” He then asked abu Ja‘far عليه السلام , “Why do you not arrange a marriage for abu ‘Abdallah عليه السلام who has grown up already?” He has said that before abu Ja‘far عليه السلام there was a bag filled with money and he said, “Very soon traders will come from Barbar and find accommodation in the house of Maymun and with the money in this bag we will buy for him a slave girl.” The narrator has said that time went by and one day we went to see abu Ja‘far عليه السلام and he said, “Do you want me to tell you about the traders of whom I spoke to you a few days ago? He has just arrived. Go and with the money in this bag buy a slave girl from him.” The narrator has said, “We went to the trader but he had sold all of his slave girls accept two of them who were ill and one of them was more beautiful than the other. We said that we would like to see them. Then we saw them and asked as to for how much he would sell the more beautiful one.” He said, “Seventy Dinars is the price.” We asked him to reduce the price but he said that he will not accept anything less than seventy Dinars. We then said, “We will give all the money that is in the bag but we do not know how much is in it.” There was a man with gray hair and beard who, said, “Open the bag and weigh it.” The trader said, “Do not open because if it would be less then seventy Dinars I will not accept.” The old man said, “Come close and we went closer and opened the bag and weighed the Dinars in it and there were exactly seventy Dinars no more and no less. We brought the slave girl to abu Ja‘far عليه السلام and Ja‘far عليه السلام was also there. We informed abu Ja‘far عليه السلام of the whole story and he offered thanks to Allah and praised Him and then he asked the girl, “What is your name?” She said, “My name is Humayda.” He said, “You are Humayda in this world and a praised one in the next life. Tell me more, “Are you virgin or not virgin?” She said, “I am virgin.” He said, “How can that be true? The traders corrupt whatever may come in their hands.” She said, “He would come to me and would sit next to me just as man and woman would do but Allah would make a man with gray hairs and beard would appear and would slap him until he would go away from me. This happened several times on his part and on the part of the man with gray hairs and beard.” The Imam عليه السلام said, “O Ja‘far عليه السلام take her for yourself.” She then give birth to the best person on earth who was Musa ibn Ja‘far عليه السلام .”
