Hajjaj bin Amr bin Ghaziyyah was sitting with Zayd bin Thabit when Ibn Qahd, a man from Yemen, came and said: O Abu Sa'id! (this is the kunyah of Zayd bin Thabit) I have some slave girls who are better than my wives, but I do not want all of them to become pregnant. May I practice coitus interruptus with them? Zayd said to Hajjaj: Give the ruling. Hajjaj said: May Allah forgive you, we come to you to learn knowledge. Zayd said: Tell (the ruling). When I said: They are your fields; if you wish, water them, and if you wish, leave them dry. I used to hear this from Zayd. Zayd said: He has spoken the truth.
