Musannaf Ibn Abi Shaybah 18368 — A man who buys or captures a slave

Dawud (may Allah have mercy on him) said: I said to al-Sha'bi (may Allah have mercy on him): Sayyiduna Abu Musa (may Allah be pleased with him) said on the day Tustar was conquered that no pregnant woman should be had intercourse with, and that there should be no sharing with the polytheists in their children, for the water adds to the child. Did he say this from his own opinion, or did he narrate it from the Messenger of Allah (peace and blessings be upon him)? He said: On the day of Awtas, the Messenger of Allah (peace and blessings be upon him) said that no pregnant woman should be had intercourse with before she gives birth, and no other woman until it is known that her womb is empty.
