According to Ismail ibn Musa al-Fazari [followed by the names of the next four oral transmitters of this account]…Al-Urani, Owner of the Camel, said…I was travelling on my camel one day when a rider appeared before me. “O Owner of the Camel,” he said, “will you sell your camel?” “Yes,” I replied. “For how much?” “A thousand dirhams.” “You must be mad,” he said, “Can a camel cost one thousand dirhams?” “ Yes…I’ve never gone after anyone without catching him,” I replied, “and no one has come after me without my escaping him…So whom do you want to buy him for?” “For your mother,” he answered. “He is yours then. Take him for nothing!,” I said.
