He said, "Abu Said! I have slave-girls. None of the wives in my keep are more pleasing to me than them, and not all of them please me so much that I want a child by them, shall I then practise coitus interruptus?" Zayd ibn Thabit said, "Give an opinion, Hajjaj!" "I said, 'May Allah forgive you! We sit with you in order to learn from you!' He said, 'Give an opinion! 'I said, 'She is your field, if you wish, water it, and if you wish, leave it thirsty. I heard that from Zayd.' Zayd said, 'He has spoken the truth.' "
