after the battle of Banu al-Mustaliq.

after the battle of Banu al-Mustaliq. The Muslims had arrested two hundred of their families. Juwayriyyah was a widow, and the Prophet married her after emancipating her. The Muslims said: These are now the relatives of the Messenger of Allah by marriage; they should not be held captive. So they freed all of them. Impressed by this nobility, the whole tribe of Banu al-Mustaliq entered into the fold of Islam.

It was a very large tribe, and this generosity of the Muslims as well as the conversion of that tribe had a great impact throughout Arabia. • To forge friendly relations: Some marriages were entered into in the hope of establishing friendly relationships with some tribes in order to blunt their enmity towards Islam. Ummu Habibah, i.e. Ramlah daughter of Abu Sufyan, was married to 'Ubaydullah ibn Jahsh and had emigrated with them to Abyssinia in the second migration.

While there, 'Ubaydullah was converted to Christianity, but she remained steadfastly on Islam and separated from him. Her father, Abu Sufyan, was in those days raising one army after another in order to annihilate the Muslims. The Prophet married her and afforded protection to her although the hope of any change in Abu Sufyan's attitude did not materialize.

Safiyyah was the daughter of Huyaiy ibn Akhtab, (Jewish) chief of Banu an-Nadhir Her husband was killed in the battle of Khaybar, and her father sided with Banu Qurayzah. She was among the captives of Khaybar. The Prophet chose her for himself and married her after emancipating her in 7 A.H. This marriage protected her from humiliation and established a link with the Jews.  To establish and implement important laws: The case of Zainab bint Jahsh is its only example.

She was a cousin of the Prophet (daughter of his paternal aunt, and sister of 'Abdullah ibn Jahsh, the first husband of Zainab bint Khuzaymah). She was a widow. Islam had annulled class differences and declared that a family's tribe, wealth, or social status are not the criteria of distinction. Every Muslim is equal. While announcing it, the Prophet, in the same sitting, gave his three relative ladies in marriage to persons of "low" birth or status.

It was done in order to practically demonstrate the Islamic equality, which up to that moment, was only a theoretical p nciple. Among them, Zainab bint Jahsh was given in marriage to Zayd ibn Harithah, an Arab slave whom the Prophet had freed and adopted as son. People called him Zayd ibn Muhammad. This marriage soon turned sour.
