Juwayriya bint al-Harith

Juwayriya bint al-Harith (; c. 608 – 676) was a wife of Muhammad and a Mother of the Believers. She married the Islamic prophet Muhammad when he was 58 years old and she was 20, thus placing the marriage in 627/8.
Family background.
She was the daughter of al-Hārith ibn Abi Dirar, the chief of Banu Mustaliq, who was defeated with his tribe in a battle.
Conflict between Muslims and Banu Mustaliq.
Two months after Muḥammad returned from the Expedition of Dhū Qarad, he began to hear rumours that the Banū al-Muṣṭaliq were preparing to attack him, so he sent a spy, Buraydah ibn Al-Ḥasīb Al-Aslamī, to confirm this. The Banū al-Muṣṭaliq also believed that Muḥammad was preparing to attack them. So they in turn sent a spy reconnoiter to explore the positions of the Muslims, but he was captured and killed by them.
The two armies were stationed at a well called Al-Muraysī', near the sea, a short distance from Mecca. They fought with bows and arrows for an hour, and then the Muslims advanced rapidly, they surrounded the al-Muṣṭaliq and took the entire tribe as prisoners, with their families, herds and flock. The battle ended in full victory for the Muslims. Two hundred families were taken as captives, two hundred camels, five thousand sheep, goats, as well as a huge quantity of household goods which were captured as booty. The household goods were sold in an auction to the highest bidder.
The Mustaliq lost a total of ten men. Only one Muslim was killed by mistake by a Helper. Juwayrīyah bint al-Ḥārith, daughter of the Banū al-Muṣṭaliq chief was one of the captives.
Juwayriya captured as slave, freed and married.
After minimal casualties, the Muslim forces were victorious. Among the many captives was Juwayriya, whose husband, Mustafa bin Safwan, had been killed in the battle. She initially fell among Muhammad's companion Thabit b. Qays b. Al-Shammas. Troubled by this, Juwayriya sought a deed of redemption from Muhammad. Muhammad proposed to marry her and, as a result, freed her from the bondage of Thabit b. Qais and consequently ameliorated the condition of her captured tribe.
This incident was described in more detail:
"At the first opportunity [after her capture] she went to the Prophet, and pleaded her case with him. She told him that she was the daughter of a chieftain and used to command and because of her unfortunate circumstance she found herself in this helpless position. From a throne made of gold she had fallen into dust. ...How could she possibly live the life as a slave? She pleaded with the Prophet, to take notice of the pitiful and desperate condition in which she found herself.
The Prophet, was moved by her sorrowful plea and asked her if she would like to live as a free woman and be part of his household if he paid her ransom. She had never in her dreams expected this offer. Moved deeply by this unexpected elevation in her status, she exclaimed she would be more than happy to accept."
Some time later her father and all the men of her tribe who had been freed also accepted Islam as their religion.
Consequently, she was married to Muhammad, the Islamic prophet when he was 58 years old and she was 20, thus placing the marriage in 628. After her marriage, it is mentioned that she was very pious and spent most of her time engrossed in prayer.
Death and burial.
She died at the age of sixty-five in the 50th year after migration and was buried with the other wives of Muhammad in Jannatul Baqi'.
Her qualities.
Juwayriya was described as being very beautiful and refined:
Legacy.
Juwayriyah bint Al-Harith reported: The Prophet came out from my apartment in the morning as I was busy in performing the dawn prayer. He came back in the forenoon and found me sitting there. The Prophet said, "Are you still in the same position as I left you." I replied in the affirmative. Thereupon the Prophet said,
"I recited four words three times after I had left you. If these are to be weighed against all you have recited since morning, these will be heavier. These are:
سُبْحَانَ اللهِ وَ بِحَمْدِهِ عَدَدَ خَلقِهِ وَرِضَا نَفْسِهِ وَزِنَةَ عَرْشِهِ وَ مِدَادَ كَلِمَاتِهِ
"Subhan-Allahi wa bihamdihi, `adada khalqihi, wa rida nafsihi, wa zinatah `arshihi, wa midada kalimatihi"
Allah is free from imperfection and I begin with His praise, as many times as the number of His creatures, in accordance with His Good Pleasure, equal to the weight of His Throne and equal to the ink that may be used in recording the words (for His Praise)." - Muslim
