“I once visited abu ‘Abd Allah (a.s.), when he had disembarked in al-Hirah and asked me, ‘What do you do for a living?’ I replied, ‘I trade in animals.’ He (the Imam) said, ‘Find for me a mule which is Fadha ’.’ I then asked saying, ‘I pray to Allah to keep my soul in service for your cause, what is Fadha’?’ He (the Imam) said, ‘It is of one color except for its white belly, white thighs of the back legs and of white harness area.’ He (the narrator) has said, ‘I said, by Allah I have not seen any mule as such.’ After (a while), I entered the ditch and saw a slave riding a mule of such description. I asked, ‘Whose mule is this?’ The slave said that it belongs to his master. I then asked, ‘Does he sell it?’ He said, ‘I do not know.’ I went to his master, bought it from him, and brought it to him (the Imam). He (the Imam) said, ‘This mule is of the qualities that I had asked for.’ I then said, ‘I pray to Allah to keep my soul in service for your cause, pray for me before Allah.’ He (the Imam) said, ‘O Allah, grant him a great deal of assets and children.’ He (the narrator) has said, ‘I then became the wealthiest of the people of al-Kufah as well in terms of children.’”
