´Narrated Umm Habibah bint Al-'Irbad:` From her father: "On the day of Khaibar, the Messenger of Allah (ﷺ) prohibited eating the meat of every predator that has canine teeth, the meat of every bird that has talons, the meat of the domestic donkey, the Mujath-thamah, the Khalisah, and from having relations with a pregnant slave until she gives birth to what is in her womb." Muhammad bin Yahya said: "Abu 'Asim was asked about Mujath-thamah and he said: "To ensnare a bird or something and then shoot it." He was asked about Khalisah, so he said: "(Prey) that a man finds with a wolf or a predator, then he takes it from him but it dies in his hand before it can be slaughtered."

It is narrated from ‘Irbad bin Sariyah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) forbade having intercourse with captive pregnant women until they give birth to the children in their wombs 1. © Imam Tirmidhi says:
1- The hadith of ‘Irbad (may Allah be pleased with him) is gharib (rare),
2- In this chapter, there is also a narration from Ruwaifi‘ bin Thabit (may Allah be pleased with him),
3- The people of knowledge act upon this, Al-Awza‘i says: When a person buys a slave woman from among the captive women and she is pregnant, there is a narration from ‘Umar bin Khattab, he said: If she is pregnant, intercourse should not take place with her until she gives birth,
4- Al-Awza‘i says: As for free women, the established Sunnah is that they are ordered to observe the waiting period (‘iddah).
