Narrated Umm Habibah bint 'Irbad bin Sariyah:

From her father who told her that the Messenger of Allah (ﷺ) prohibited intercourse with female prisoners, until they deliver what is in their wombs."

[Abu 'Eisa said:] There is something on this topic from Ruwaifi' bin Thabit, and the Hadith of 'Irbad is a Gharib Hadith. This is acted upon according to the people of knowledge.

Al-Awza'i said: "When a man purchases a slave girl from the captives and she is pregnant, then it has been related from 'Umar bin Al-Khattab that he said: 'Do not have intercourse with the pregnant women until she gives birth.'" Al-Awza'i said: "As for the free women, then the Sunnah about them has passed, in that the 'Iddah is observed." All of this was narrated to me by 'Ali bin Khushram who said: " 'Eisa bin Yunus narrated to us from Al-Awza'i."
