Expedition of al-Muraysi'

The Expedition of al-Muraysi‘ was an early Muslim campaign against the tribe of Banu Mustaliq which took place in January 627 CE.

Surprise attack
On hearing the advent of the Muslims, the tribe was terrified, and the Arabs that accompanied them defected and fled for their lives. Abu Bakr was entrusted as the commander of the Muhajir's (Emigrants), and Sa‘d bin ‘Ubādah was the commander of the Anṣar (Helpers). 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 so 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.

'Alī ibn Abī Ṭālib killed a few wounded Banū al-Muṣṭaliq; among whom were Mālik and his son.

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.

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, and agreed to marry Muḥammad in exchange for releasing 100 prisoners who converted to Islam, as compensation (according to the Muslim scholar Saifur Rahman al Mubarakpuri).

Altercation between the fighters on return to Medina
The army remained at the well of Al-Muraysī' for several days, during which an altercation ensued between the Muhājir and Anṣār. One of the Muhājirs, named Jahja, attacked an Ansārī, and the two groups immediately clashed, but the quarrel was broken up by Muḥammad.

'Abdullāh ibn ‘Ubayy, who was referred to as the head of the Hypocrites (al-Munāfiqūn) by Muslim historians, was furious for the challenge which the Muslims showed towards the hostile plans and vicious intrigues woven behind closed doors, and swore "the most honourable will expel the meanest out of Madinah", and added: "They (the Muslims) have outnumbered and shared us our land. If you fatten your dog, it will eat you." When that talk was reported to the Muḥammad, 'Umar asked for permission to have Ibn ‘Ubayy killed. Muhammad turned down his proposal on the grounds that it was not becoming for a prophet to be accused of killing his people.

'Abdullāh ibn Ubayy's son, who was also called 'Abdullāh, was angry at his father for the disrespect he showed. When the army reached Madinah, he drew his sword against his father and barred his father's entry into the town until he had confessed and declared that he himself was the meanest of the citizens of Madinah and that Muḥammad was the most honourable of them. The son was ready to cut off his father's head and bring it to Muḥammad, if he so wished.

He said, according to the Muslim Historian al-Ṭabarī:

According to the Sealed Nectar, Muḥammad did not punish Abdullāh ibn Ubayy in the public interest. 'Umar ibn Al-Khattāb asked Muḥammad why he did not accept his offer to kill him, to which he replied:
