After the war with Banu Quraiza had been settled and they had been defeated, Sa‘d bin Mu‘adh’s wish was gratified and he gave his last breath. In response to his supplication ‘Aishah [R] narrated, Sa‘d’s wounds began to bleed from the front part of his neck while he was in his tent which the Prophet [pbuh] had pitched for him in the mosque so that he would be in close proximity in order to inquire about and watch his well-being closely. The people were not scared except when the blood flowed towards them, and in the Mosque along with Sa‘d’s tent, there was the tent of Banu Ghifar. They said: O people of the tent, what is it that is coming to us from you? Lo! it was Sa‘d’s wound that was bleeding and he died thereon.[Sahih Al-Bukhari 2/591]
Jabir narrated that the Messenger of Allâh [pbuh] had said: "The Throne of the Compassionate shook for the death of Sa‘d bin Mu‘adh.[Sahih Al-Bukhari 1/536; Sahih Muslim 2/294;
Jami' At-Tirmidhi 2/225]" When his bier was carried, At-Tirmidhi said: The hypocrites alleged it was too light. The Messenger of Allâh [pbuh] retorted:
"The angels are carrying him."
In the process of the sieze laid to Banu Quraiza, one man of the Muslims, Khallad bin Suwaid was killed when a women of the Jews dropped the grinding stone on him, and another, Abu Sinan bin Mihsan, the brother of ‘Ukasha, died.
Abu Lubaba stayed tied for six nights. His wife used to untie him at prayer times and then he tied himself again to the pole. One early morning, Allâh the All-Forgiving revealed a verse to the Messenger of Allâh [pbuh] to the effect that Allâh had turned to Abu Lubaba with forgiveness. The Muslims rushed to release him but he insisted that the Messenger of Allâh [pbuh] himself do it. And this was done shortly before the morning prayer.
This Ghazwah took place in the month of Dhul Qa‘dah in the year five Hijri[Ibn Hisham
2/237,238; Sahih Al-Bukhari 2/590,591; Za'd Al-Ma'ad 2/72-74; Mukhtasar Seerat Ar-Rasool p.287-290], and the siege of Banu Quraiza’s forts lasted for 25 days. The Chapter of Confederates was revealed containing Allâh’s Words concerning the basic issues relating to the believers and hypocrites during the battle of the Confederates, and the consequences of the treachery and breaching of covenants by the Jews.
