ahya related to me from Malik that he asked Ibn Shihab about thedhihar of a slave. He said, "It is like the dhihar of a free man."Malik said, "He meant that the same conditions were appliedin both cases."Malik said, "The dhihar of the slave isincumbent on him, and the fasting of the slave in the dhihar is twomonths. "Malik said that there was no ila for a slave whopronounced a dhihar from his wife. That was because if he were to fastthe kaffara for pronouncing a dhihar, the divorce of the ila wouldcome to him before he had finished the fast.
