Yahya related to me from Malik from Ibrahim ibn Abi Abla from Abdal-Malik ibn Marwan that he gave a slave-girl to a friend of his, andlater asked him about her. He said, "I intended to give her to my sonto do such-and-such with her." Abd al-Malik said, "Marwan was morescrupulous than you. He gave a slave-girl to his son, and then hesaid, 'Do not go near her, for I have seen her leg uncovered .' "
