The Siege of Banu Qurayza was a military siege undertaken by the early Muslims against the fortress of Banu Qurayza, an Arabian Jewish tribe, in January 627 (Dhul Qa‘dah 5 AH). It followed on from the Battle of the Trench.

The Banu Qurayza, a Jewish tribe that once lived in Medina. though previously allied with the Muslims, al-Waqidi states that Muhammad had a treaty with the tribe which was torn up by them. Norman Stillman and Watt believe that the existence of such a treaty was "doubtful", though Watt believes that Banu Qurayza had agreed not to assist Muhammad's enemies.Stillman, The Jews of Arab Lands: A History and Source Book, pp. 14-16. According to Safiur Rahman Mubarakpuri, Peters, Stillman, Guillaume, Inamdar and Ibn Kathir, on the day of the Meccans' withdrawal Muhammad led his forces against Banu Qurayza. According to Muslim tradition he had been ordered to do so by God.Peters, Muhammad and the Origins of Islam, p. 222-224.Stillman, The Jews of Arab Lands: A History and Source Book, p. 140. Ibn Kathir gives the reason as: "Banu Qurayza broke the covenant that existed between them and the messenger of Allah".

The Banu Qurayza were besieged for 25 days until they surrendered. The men from Banu Aws, who were one of the two Arab tribes in Medina who had become followers of Muhammad and part of the Ansar, requested that Muhammad treat Banu Qurayza leniently, as they were their client tribe. Muhammad then proposed that one man from the Banu Aws pass the judgment, and they agreed. They then appointed Sa'd ibn Muadh, who was gravely wounded by an arrow. So Sa'd stated that his decision would be, "The men should be killed, the property divided, and the women and children taken as slaves." Muhammad approved of the ruling, calling it in accordance with God's decree pronounced above the seventh heaven.Adil, Muhammad: The Messenger of Islam, p. 395f. After that, nearly all male members of the tribe who had reached puberty were handcuffed and later beheaded in a massacre.Kister (1990), Society and religion from Jāhiliyya to Islam, p. 54. The Muslim jurist al-Tabari quotes 600–900 being killed. (online) The Sunni hadiths do not give the number killed, but state that one woman and all pubescent fighting males were killed.Sunan Abu Dawud 14:2665, "No woman of Banu Qurayzah was killed except one. She was with me, talking and laughing on her back and belly (extremely), while the Apostle of Allah (peace_be_upon_him) was killing her people with the swords. Suddenly a man called her name: Where is so-and-so? She said: I I asked: What is the matter with you? She said: I did a new act. She said: The man took her and beheaded her. She said: I will not forget that she was laughing extremely although she knew that she would be killed. " According to Ibn Kathir, Quranic verses 33:26-27 and 33:9-10 are about the expedition against the Banu Qurayza.(online )

Banu Qurayza

The Banu Qurayza ( alternate spellings include Quraiza, Qurayzah, Quraytha, and the archaic Koreiza) were a Jewish tribe that lived in northern Arabia, at the oasis of Yathrib (known today as Medina).

Jewish tribes reportedly arrived in Hijaz in the wake of the Jewish-Roman wars and might have introduced agriculture, which may have put them in a culturally, economically and politically dominant position.Watt, Encyclopaedia of Islam, Section on "Kurayza, Banu". The Banu Qurayza, however, did not own any land.Watt (1961), p.98

Background Agreement with Muhammad The Banu Qurayza reportedly signed a treaty with Muhammad. According to Watt, it is unclear whether or not their treaty with Muhammad obliged the Qurayza to help him defend Medina or merely to remain neutral; according to Ramadan, they had signed an agreement of mutual assistance with Muhammad. This stance is supported by medieval sources Ibn Ishaq/Ibn Hisham and al-Waqidi. Both Watt and Stillman believe that no special agreement existed between Muhammad and the Qurayza. Watt, however, does agree that the Qurayza had agreed not to support Muhammad's enemies against him. Zafar Ali Qureshi, has criticized Watt's assessment and approach to such incidents.

In 627, Abu Sufyan led an attack on Medina during the Battle of the Trench. The Qurayza did not participate in the fighting - according to David Norcliffe, but they allegedly lent tools to the Muslims, to defend themselves in Medina. The Qurayza were deeply offended by Muhammad's recitation of revelations which criticized some Jews. According to Al-Waqidi, the Banu Qurayza helped the defense effort of Medina by supplying spades, picks, and baskets for the excavation of the defensive trench the defenders of Medina had dug in preparation. According to Watt, the Banu Qurayza "seem to have tried to remain neutral" in the battle (free online) but later changed their attitude when a Jew from Khaybar persuaded them that Muhammad was sure to be overwhelmed, making them doubt whether they should help and ally with MuhammadWatt, Muhammad, Prophet and Statesman, p. 170-176. and though they did not commit any act overtly hostile to Muhammad, according to Watt, they entered into negotiations with the invading army to reach a settlement. Musnad Ahmad number 22823 also mentions that the Qurayza allegedly helped Muhammad by turning down Abu Sufyan when he wanted their help to attack Muhammad, and that Abu Sufyan was not happy with them.Musnad Ahmad ibn Hanbal, no. 22823, al-islam.com (archive)

According to Shibli Nomani, Ibn Ishaq writes that during the siege, the Qurayza readmitted Huyayy ibn Akhtab, the chief of the Banu Nadir whom Muhammad had exiled (during the Invasion of Banu Nadir),Nomani, Sirat al-Nabi, p. 382.

Decision to terminate alliance Al-Waqidi reports that Huyayy tore up the agreement between Ka'b and Muhammad. Rumours began to spread that the Qurayza had decided to terminate their treaty with Muhammad. So Muhammad sent some men to confirm this. According to William Muir, the Qurayza said to the men "Who is Mahomet, and who is the Apostle of God, that we should obey him? There is no bond or compact between us and him." Norman Stillman denies the claims of al-Waqidi and that there ever was an agreement. Watt also rejects the existence of such a special agreement, but notes that the Qurayza had a general agreement with Muhammad because they were allied to 2 Muslim tribes (the Banu Aws and Banu Khazraj).

Decision to attack According to Peters and Stillman, on the day of the Meccans' withdrawal, Muhammad led his forces against the Banu Qurayza neighborhood. According to the Muslim tradition, he had been ordered to do so by the angel Gabriel.

According to The Sealed Nectar, a modern Islamic biography of Muhammad written by the Indian Muslim author Saif ur-Rahman Mubarakpuri, the Angel Gabriel visited Muhammad while he was washing clothes at Umm Salama’s house, asking that he should unsheathe his sword and go to the Banu Qurayza and fight them. Mubarakpuri claims Gabriel said that he, with a procession of angels, would go ahead to the fort of the Banu Qurayza and cast fear in their hearts. This is also mentioned in the Sunni hadith collections in .

Ibn Kathir, mentioned the sequence of events in his Tafsir, as follows:

Muhammad immediately summoned the prayer caller and ordered him to announce fresh hostilities against the Banu Qurayza, instituted Ibn Umm Maktum as a ruler of Medina, and entrusted the banner of war to ‘Ali bin Abi Talib, who marched towards the appointed target and came close enough to hear the Banu Qurayza abusing Muhammad, who on his part set out at the head of 3,000 infantry men and 30 horsemen of Ansar (Helpers) and Muhajireen (Emigrants).

Siege of Banu Qurayza When they reached the habitations of Banu Quraiza, they laid tight siege to their forts. The Banu Qurayza retreated into their stronghold and endured the siege for 25 days. As their morale waned, Ka'b ibn Asad (the chief of the tribe) suggested three alternative ways out of their predicament: embrace Islam, kill their own children and women, then rush out for a charge to either win or die; or make a surprise attack on the Sabbath. The Banu Qurayza accepted none of these alternatives. Instead they asked to confer with Abu Lubaba, one of their allies from the Aws. According to Ibn Ishaq, Abu Lubaba felt pity for the women and children of the tribe who were crying and when asked whether the Qurayza should surrender to Muhammad, advised them to do so. However he also "made a sign with his hand toward his throat, indicating that [their fate] would be slaughter". According to Mubarakpuri, Abu Lubab begged Muhammad for forgiveness (on behalf of the Qurayza), but Muhammad said it is only God who can forgive him. The next morning, the Banu Qurayza surrendered and the Muslims seized their stronghold and their stores.Kister, Meir J., "The Massacre of the Banu Quraiza. A re-examination of a tradition", in: Jerusalem Studies in Arabic and Islam 8 (1986), p. 94 ,"These included weapons, household goods, utensils, camels and cattle. The stored wine was spilled". The men - numbering between 400 and 900 - were bound and placed under the custody of Muhammad ibn Maslamah, who had killed Ka'b ibn al-Ashraf, while the women and children - numbering about 1,000Kister, Meir J., "The Massacre of the Banu Quraiza. A re-examination of a tradition", in: Jerusalem Studies in Arabic and Islam 8 (1986), p. 93 (footnotes). (also referenced in Society and religion from Jāhiliyya to Islam, p. 45) - were placed under Abdullah ibn Sallam, a former rabbi who had converted to Islam.

According to Mubrakpuri, Muslims continued their siege for many days and were getting tired. Ali and Zubayr ibn al-Awwam proceeded with ‘Ali swearing that he would never stop until he had either stormed their garrisons or been martyred like Hamza.

Muhammad meanwhile asked one of his poets, Hasam bin Thabit to abuse them with his poems. This is mentioned in

Execution of the Banu Qurayza

Surrender and execution

After their garrisons were stormed by Ali they had no choice but to comply with Muhammad's judgement. Muhammad ordered that the men should be handcuffed, and this was done under the supervision of Muhammad bin Salamah Al-Ansari while the women and children were isolated in confinement. Thereupon Al-Aws tribe interceded begging Muhammad to be lenient towards them. He suggested that Sa‘d bin Mu‘adh, a Muslim convert who was a former ally of the tribe, should decide their fate.

According to Mubrakpuri, Stillman, Peters and Adil and Muir, when Sa'd arrived, his fellow Aws pleaded for leniency towards the Qurayza and on his request pledged that they would abide by his decision.Peterson, Muhammad: the prophet of God, p. 125-127. He then pronounced that "the men should be killed, the property divided, and the women and children taken as captives". Muhammad approved of the ruling, calling it similar to God's judgment. Mubarakpuri states that the tribesmen who had reached puberty were beheaded.

Martin Lings, in his book "Muhammad: his life based on the earliest sources", page 231 and 232 said : Sa‘d was a man of mighty stature, of handsome and majestic appearance, and when he came to the camp the Prophet said "Rise in honour of your liege lord," and they rose to greet him saying: "Father of ‘Amr, the Messenger of God hath appointed thee to judge the case of thy confederates." He said: "Do ye then swear by God and make by Him your covenant that my judgement shall be the verdict upon them?" "We do," they answered. "And is it binding upon him who is here?" he added, with a glance in the direction of the Prophet, but not mentioning him out of reverence. "It is," said the Prophet. "Then I judge," said Sa‘d, "that the men shall be slain, the property divided, and the women and children made captive."1 The Prophet said to him: "Thou hast judged with the judgement of God from above the seven heavens." Lings added the footnote 1 at the bottom of the page 232
