Abu Sa’id Al Khudri traced to Prophet (ﷺ) the following statement regarding the captives taken at Atwas. There must be no intercourse with pregnant woman till she gives birth to her child or with the one who is not pregnant till she has had one menstrual period.
AbdurRahman ibn Ghanam said: We were stationed at the frontiers of the city of Qinnisrin with Shurahbil ibn as-Simt. When he conquered it, he got sheep and cows there. He distributed some of them amongst us, and deposited the rest of them in the spoils of war. I met Mu’adh ibn Jabal and mentioned it to him. Mu’adh said: we went on an expedition of Khaybar along with the Messenger of Allah (ﷺ) and we got spoils there. The Messenger of Allah (ﷺ) divided them among us and placed the rest of them in the booty.
The Prophet (ﷺ) was brought a necklace in which there were gold and pearls. (The narrators AbuBakr and (Ahmad) Ibn Mani’ said: The pearls were set with gold in it, and a man bought it for nine or seven dinars.) The Prophet (ﷺ) said: (It must not be sold) till the contents are considered separately. The narrator said: He returned it till the contents were considered separately. The narrator Ibn Asa said: By this I intended trade. Abu Dawud said: The word hijarah (stone) was recorded in his note-book before, but he changed it and narrated tijarah (trade).
At the battle of Khaibar I bought a necklace in which there were gold and pearls for twelve dinars. I separated them and found that its worth was more than twelve dinars. So I mentioned that to the Prophet (ﷺ) who said: It must not be sold till the contents are considered separately.
