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

لَمَّا رَجَعَ النَّبِيُّ ﷺ مِنَ الْخَنْدَقِ وَوَضَعَ السِّلاَحَ وَاغْتَسَلَ أَتَاهُ جِبْرِيلُ عَلَيْهِ السَّلاَمُ فَقَالَ قَدْ وَضَعْتَ السِّلاَحَ وَاللَّهِ مَا وَضَعْنَاهُ فَاخْرُجْ إِلَيْهِمْ قَالَ فَإِلَى أَيْنَ قَالَ هَا هُنَا وَأَشَارَ إِلَى بَنِي قُرَيْظَةَ فَخَرَجَ النَّبِيُّ ﷺ إِلَيْهِمْ  

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 Messenger of Allah ﷺ set out to Banu Quraiza (to attack them).  

كَأَنِّي أَنْظُرُ إِلَى الْغُبَارِ سَاطِعًا فِي زُقَاقِ بَنِي غَنْمٍ مَوْكِبِ جِبْرِيلَ حِينَ سَارَ رَسُولُ اللَّهِ ﷺ إِلَى بَنِي قُرَيْظَةَ  

On the day of Al-Ahzab (i.e. Clans) the Prophet ﷺ said, "None of you Muslims) should offer the ʿAsr prayer but at Banu Quraiza's place." The ʿAsr 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 ﷺ did not mean that for us." Later on It was mentioned to the Prophet ﷺ and he did not berate any of the two groups.  

قَالَ النَّبِيُّ ﷺ يَوْمَ الأَحْزَابِ لاَ يُصَلِّيَنَّ أَحَدٌ الْعَصْرَ إِلاَّ فِي بَنِي قُرَيْظَةَ فَأَدْرَكَ بَعْضُهُمُ الْعَصْرَ فِي الطَّرِيقِ فَقَالَ بَعْضُهُمْ لاَ نُصَلِّي حَتَّى نَأْتِيَهَا وَقَالَ بَعْضُهُمْ بَلْ نُصَلِّي لَمْ يُرِدْ مِنَّا ذَلِكَ فَذُكِرَ ذَلِكَ لِلنَّبِيِّ ﷺ فَلَمْ يُعَنِّفْ وَاحِدًا مِنْهُمْ  

Some (of the Ansar) used to present date palm trees to the Prophet ﷺ 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 ﷺ to return some or all the date palms they had given to him, but the Prophet ﷺ 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 ﷺ ) has given them to me." The Prophet ﷺ 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.  

كَانَ الرَّجُلُ يَجْعَلُ لِلنَّبِيِّ ﷺ النَّخَلاَتِ حَتَّى افْتَتَحَ قُرَيْظَةَ وَالنَّضِيرَ وَإِنَّ أَهْلِي أَمَرُونِي أَنْ آتِيَ النَّبِيَّ ﷺ فَأَسْأَلَهُ الَّذِينَ كَانُوا أَعْطَوْهُ أَوْ بَعْضَهُ وَكَانَ النَّبِيُّ ﷺ قَدْ أَعْطَاهُ أُمَّ أَيْمَنَ فَجَاءَتْ أُمُّ أَيْمَنَ فَجَعَلَتِ الثَّوْبَ فِي عُنُقِي تَقُولُ كَلاَّ وَالَّذِي لاَ إِلَهَ إِلاَّ هُوَ لاَ يُعْطِيكَهُمْ وَقَدْ أَعْطَانِيهَا أَوْ كَمَا قَالَتْ وَالنَّبِيُّ ﷺ يَقُولُ لَكِ كَذَا وَتَقُولُ كَلاَّ وَاللَّهِ حَتَّى أَعْطَاهَا حَسِبْتُ أَنَّهُ قَالَ عَشَرَةَ أَمْثَالِهِ أَوْ كَمَا قَالَ  

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

سَمِعْتُ أَبَا سَعِيدٍ الْخُدْرِيَّ ؓ يَقُولُ نَزَلَ أَهْلُ قُرَيْظَةَ عَلَى حُكْمِ سَعْدِ بْنِ مُعَاذٍ فَأَرْسَلَ النَّبِيُّ ﷺ إِلَى سَعْدٍ فَأَتَى عَلَى حِمَارٍ فَلَمَّا دَنَا مِنَ الْمَسْجِدِ قَالَ لِلأَنْصَارِ قُومُوا إِلَى سَيِّدِكُمْ أَوْ خَيْرِكُمْ فَقَالَ هَؤُلاَءِ نَزَلُوا عَلَى حُكْمِكَ فَقَالَ تَقْتُلُ مُقَاتِلَتَهُمْ وَتَسْبِي ذَرَارِيَّهُمْ قَالَ قَضَيْتَ بِحُكْمِ اللَّهِ وَرُبَّمَا قَالَ بِحُكْمِ الْمَلِكِ  

Saʿd was wounded on the day of Khandaq (i.e. Trench) when a man from Quraish, called Hibban bin Al-ʿAraqa 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 Saʿd's medial arm vein (or main artery of the arm). The Prophet ﷺ pitched a tent (for Saʿd) in the Mosque so that he might be near to the Prophet ﷺ 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 ﷺ said, "Where?" Gabriel pointed towards Bani Quraiza. So Messenger of Allah ﷺ went to them (i.e. Banu Quraiza) (i.e. besieged them). They then surrendered to the Prophet's judgment but he directed them to Saʿd to give his verdict concerning them. Saʿd 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 ʿAisha said, "Saʿd 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 Saʿd's wound. Saʿd then died because of that."

The Prophet ﷺ said to Hassan, "Abuse them (with your poems), and Gabriel is with you (i.e, supports you)." (Through another group of sub narrators) Al-Bara bin Azib said, "On the day of Quraiza's (besiege), Messenger of Allah ﷺ said to Hassan bin Thabit, 'Abuse them (with your poems), and Gabriel is with you (i.e. supports you).' "  

قَالَ النَّبِيُّ ﷺ لِحَسَّانَ اهْجُهُمْ أَوْ هَاجِهِمْ وَجِبْرِيلُ مَعَكَ  

"On the day of Quraiza's (siege), Messenger of Allah ﷺ said to Hassan bin Thabit, 'Abuse them (with your poems), and Jibril is with you.'"  

قَالَ رَسُولُ اللَّهِ ﷺ يَوْمَ قُرَيْظَةَ لِحَسَّانَ بْنِ ثَابِتٍ اهْجُ الْمُشْرِكِينَ فَإِنَّ جِبْرِيلَ مَعَكَ
