I wrote a letter to Nafi` and Nafi` wrote in reply to my letter that the Prophet (ﷺ) had suddenly attacked
Bani Mustaliq without warning while they were heedless and their cattle were being watered at the
places of water. Their fighting men were killed and their women and children were taken as captives;
the Prophet (ﷺ) got Juwairiya on that day. Nafi` said that Ibn `Umar had told him the above narration and
that Ibn `Umar was in that army. - Hadith Al Bukhari 2541 (islam)
Book 49, Hadith 24
Vol. 3, Book 46, Hadith 717

The Prophet (ﷺ) visited her (Juwairiya) on a Friday and she was fasting. He asked her, "Did you fast
yesterday?" She said, "No." He said, "Do you intend to fast tomorrow?" She said, "No." He said,
"Then break your fast." Through another series of narrators, Abu Aiyub is reported to have said, "He
ordered her and she broke her fast." - Hadith Al Bukhari 1986 (islam)
Book 30, Hadith 93
Vol. 3, Book 31, Hadith 207

Juwayriyyah, daughter of al-Harith ibn al-Mustaliq, fell to the lot of Thabit ibn Qays ibn Shammas, or to her cousin. She entered into an agreement to purchase her freedom. She was a very beautiful woman, most attractive to the eye.
Aisha said: She then came to the Messenger of Allah (ﷺ) asking him for the purchase of her freedom. When she was standing at the door, I looked at her with disapproval. I realised that the Messenger of Allah (ﷺ) would look at her in the same way that I had looked.
She said: Messenger of Allah, I am Juwayriyyah, daughter of al-Harith, and something has happened to me, which is not hidden from you. I have fallen to the lot of Thabit ibn Qays ibn Shammas, and I have entered into an agreement to purchase of my freedom. I have come to you to seek assistance for the purchase of my freedom.
The Messenger of Allah (ﷺ) said: Are you inclined to that which is better? She asked: What is that, Messenger of Allah? He replied: I shall pay the price of your freedom on your behalf, and I shall marry you.
She said: I shall do this. She (Aisha) said: The people then heard that the Messenger of Allah (ﷺ) had married Juwayriyyah. They released the captives in their possession and set them free, and said: They are the relatives of the Messenger of Allah (ﷺ) by marriage. We did not see any woman greater than Juwayriyyah who brought blessings to her people. One hundred families of Banu al-Mustaliq were set free on account of her.
Abu dawud said: This evidence shows that a Muslim ruler may marry a slave woman himself.
- Hadith Abu Dawud 3931 (islam)
Book 31, Hadith 6
Book 30, Hadith 3920

0 Abu Sa'id, did you hear Allah's Messenger (ﷺ) mentioning al-'azl? He said: Yes, and added: We went out with Allah's Messenger (ﷺ) on the expedition to the Bi'l-Mustaliq and took captive some excellent Arab women; and we desired them, for we were suffering from the absence of our wives, (but at the same time) we also desired ransom for them. So we decided to have sexual intercourse with them but by observing 'azl (Withdrawing the male sexual organ before emission of semen to avoid-conception). But we said: We are doing an act whereas Allah's Messenger is amongst us; why not ask him? So we asked Allah's Mes- senger (ﷺ), and he said: It does not matter if you do not do it, for every soul that is to be born up to the Day of Resurrection will be born. - Hadith Muslim 1438a (islam)
Book 16, Hadith 146
Book 8, Hadith 3371

And [also prohibited to you are all] married women except those your right hands possess. [This is] the decree of Allah upon you. And lawful to you are [all others] beyond these, [provided] that you seek them [in marriage] with [gifts from] your property, desiring chastity, not unlawful sexual intercourse. So for whatever you enjoy [of marriage] from them, give them their due compensation as an obligation. And there is no blame upon you for what you mutually agree to beyond the obligation. Indeed, Allah is ever Knowing and Wise. - Quran An-Nisa(The Women) 4:24 (islam)
