Muhammad ibn ʿAbd Allāh ibn Numayr and Zuhayr ibn Ḥarb narrated to me—and the wording is that of Ibn Numayr—they said: ʿAbd Allāh ibn Yazīd al-Maqburī narrated to us, Ḥaywah narrated to us, ʿAyyāsh ibn ʿAbbās narrated to me, that Abū al-Naḍr narrated to him, from ʿĀmir ibn Saʿd, that Usāmah ibn Zayd informed his father, Saʿd ibn Abī Waqqāṣ, that a man came to the Messenger of Allāh, peace and blessings be upon him, and said: "I practice coitus interruptus with my wife." The Messenger of Allāh, peace and blessings be upon him, said to him: "Why do you do that?" The man said: "I fear for her child, or for her children." The Messenger of Allāh, peace and blessings be upon him, said: "If that were harmful, it would harm Persia and Rome." And Zuhayr said in his narration: "If that were the case, then no—that has not harmed Persia, nor Rome."
