During the battle of Al-Ahzab, I and `Umar bin Abi-Salama were kept behind with the women. Behold! I saw (my father) Az-Zubair riding his horse, going to and coming from Bani Quraiza twice or thrice. So when I came back I said, "O my father! I saw you going to and coming from Bani Quraiza?" He said, "Did you really see me, O my son?" I said, "Yes." He said, "Allah's Apostle said, 'Who will go to Bani Quraiza and bring me their news?' So I went, and when I came back, Allah's Apostle mentioned for me both his parents saying, "Let my father and mother be sacrificed for you."'

People used to give some of their datepalms to the Prophet (as a gift), till he conquered Bani Quraiza and Bani An-Nadir, whereupon he started returning their favors.

Bani An-Nadir and Bani Quraiza fought (against the Prophet violating their peace treaty), so the Prophet exiled Bani An-Nadir and allowed Bani Quraiza to remain at their places (in Medina) taking nothing from them till they fought against the Prophet again) . He then killed their men and distributed their women, children and property among the Muslims, but some of them came to the Prophet and he granted them safety, and they embraced Islam. He exiled all the Jews from Medina. They were the Jews of Bani Qainuqa', the tribe of `Abdullah bin Salam and the Jews of Bani Haritha and all the other Jews of Medina.

The people of (Banu) Quraiza agreed to accept the verdict of Sa`d bin Mu`adh. So the Prophet sent for Sa`d, and the latter came (riding) a donkey and when he approached the Mosque, the Prophet said to the Ansar, "Get up for your chief or for the best among you." Then the Prophet said (to Sa`d)." These (i.e. Banu Quraiza) have agreed to accept your verdict." Sa`d said, "Kill their (men) warriors and take their offspring as captives, "On that the Prophet said, "You have judged according to Allah's Judgment," or said, "according to the King's judgment."

As if I am just now looking at the dust rising in the street of Banu Ghanm (in Medina) because of the marching of Gabriel's regiment when Allah's Apostle set out to Banu Quraiza (to attack them).

Some people used to allot some date palm trees to the Prophet as gift till he conquered Banu Quraiza and Bani An-Nadir, where upon he started returning their date palms to them.

It has been narrated on the authority of Ibn Umar that the Jews of Banu Nadir and Banu Quraiza fought against the Messenger of Allah (may peace be upon him) who expelled Banu Nadir, and allowed Quraiza to stay on, and granted favour to them until they too fought against him Then he killed their men, and distributed their women, children and properties among the Muslims, except that some of them had joined the Messenger of Allah (may peace be upon him) who granted them security. They embraced Islam. The Messenger of Allah (may peace be upon him) turned out all the Jews of Medina. Banu Qainuqa' (the tribe of 'Abdullah b. Salim) and the Jews of Banu Haritha and every other Jew who was in Medina.

When the Prophet returned from Al-Khandaq (i.e. Trench) and laid down his arms and took a bath, Gabriel came and said (to the Prophet ), You have laid down your arms? By Allah, we angels have not laid them down yet. So set out for them." The Prophet said, "Where to go?" Gabriel said, "Towards this side," pointing towards Banu Quraiza. So the Prophet went out towards them.

On the day of Al-Ahzab (i.e. Clans) the Prophet said, "None of you Muslims) should offer the `Asr prayer but at Banu Quraiza's place." The `Asr prayer became due for some of them on the way. Some of those said, "We will not offer it till we reach it, the place of Banu Quraiza," while some others said, "No, we will pray at this spot, for the Prophet did not mean that for us." Later on It was mentioned to the Prophet and he did not berate any of the two groups.

When Allah's Apostle returned on the day (of the battle) of Al-Khandaq (i.e. Trench), he put down his arms and took a bath. Then Gabriel whose head was covered with dust, came to him saying, "You have put down your arms! By Allah, I have not put down my arms yet." Allah's Apostle said, "Where (to go now)?" Gabriel said, "This way," pointing towards the tribe of Bani Quraiza. So Allah's Apostle went out towards them .

The people of (the tribe of) Quraiza agreed upon to accept the verdict of Sa`d. The Prophet sent for him (Sa`d) and he came. The Prophet said (to those people), "Get up for your chief or the best among you!" Sa`d sat beside the Prophet and the Prophet said (to him), "These people have agreed to accept your verdict." Sa`d said, "So I give my judgment that their warriors should be killed and their women and children should be taken as captives." The Prophet said, "You have judged according to the King's (Allah's) judgment." (See Hadith No. 447, Vol. 5)

When the tribe of Bani Quraiza was ready to accept Sa`d's judgment, Allah's Apostle sent for Sa`d who was near to him. Sa`d came, riding a donkey and when he came near, Allah's Apostle said (to the Ansar), "Stand up for your leader." Then Sa`d came and sat beside Allah's Apostle who said to him. "These people are ready to accept your judgment." Sa`d said, "I give the judgment that their warriors should be killed and their children and women should be taken as prisoners." The Prophet then remarked, "O Sa`d! You have judged amongst them with (or similar to) the judgment of the King Allah."

Some people (i.e. the Jews of Bani bin Quraiza) agreed to accept the verdict of Sa`d bin Mu`adh so the Prophet sent for him (i.e. Sa`d bin Mu`adh). He came riding a donkey, and when he approached the Mosque, the Prophet said, "Get up for the best amongst you." or said, "Get up for your chief." Then the Prophet said, "O Sa`d! These people have agreed to accept your verdict." Sa`d said, "I judge that their warriors should be killed and their children and women should be taken as captives." The Prophet said, "You have given a judgment similar to Allah's Judgment (or the King's judgment).

Some (of the Ansar) used to present date palm trees to the Prophet till Banu Quraiza and Banu An- Nadir were conquered (then he returned to the people their date palms). My people ordered me to ask the Prophet to return some or all the date palms they had given to him, but the Prophet had given those trees to Um Aiman. On that, Um Aiman came and put the garment around my neck and said, "No, by Him except Whom none has the right to be worshipped, he will not return those trees to you as he (i.e. the Prophet ) has given them to me." The Prophet go said (to her), "Return those trees and I will give you so much (instead of them)." But she kept on refusing, saying, "No, by Allah," till he gave her ten times the number of her date palms.

Sa`d was wounded on the day of Khandaq (i.e. Trench) when a man from Quraish, called Hibban bin Al-`Araqa hit him (with an arrow). The man was Hibban bin Qais from (the tribe of) Bani Mais bin 'Amir bin Lu'ai who shot an arrow at Sa`d's medial arm vein (or main artery of the arm). The Prophet pitched a tent (for Sa`d) in the Mosque so that he might be near to the Prophet to visit. When the Prophet returned from the (battle) of Al-Khandaq (i.e. Trench) and laid down his arms and took a bath Gabriel came to him while he (i.e. Gabriel) was shaking the dust off his head, and said, "You have laid down the arms?" By Allah, I have not laid them down. Go out to them (to attack them)." The Prophet said, "Where?" Gabriel pointed towards Bani Quraiza. So Allah's Apostle went to them (i.e. Banu Quraiza) (i.e. besieged them). They then surrendered to the Prophet's judgment but he directed them to Sa`d to give his verdict concerning them. Sa`d said, "I give my judgment that their warriors should be killed, their women and children should be taken as captives, and their properties distributed." Narrated Hisham: My father informed me that `Aisha said, "Sa`d said, "O Allah! You know that there is nothing more beloved to me than to fight in Your Cause against those who disbelieved Your Apostle and turned him out (of Mecca). O Allah! I think you have put to an end the fight between us and them (i.e. Quraish infidels). And if there still remains any fight with the Quraish (infidels), then keep me alive till I fight against them for Your Sake. But if you have brought the war to an end, then let this wound burst and cause my death thereby.' So blood gushed from the wound. There was a tent in the Mosque belonging to Banu Ghifar who were surprised by the blood flowing towards them . They said, 'O people of the tent! What is this thing which is coming to us from your side?' Behold! Blood was flowing profusely out of Sa`d's wound. Sa`d then died because of that."
