Invading Banu Quraiza
Archangel Gabriel [AWS], on the very day the Messenger of Allâh [pbuh] came back to Madinah after the previous battle, and while he was washing in Umm Salama’s house, visited him asking that he should unsheathe his sword and head for the habitation of the seditious Banu Quraiza and fight them. Gabriel noted that he with a procession of angels would go ahead to shake their forts and cast fear in their hearts.
The Messenger of Allâh [pbuh], immediately summoned the prayer caller and ordered him to announce fresh hostilities against Banu Quraiza, institued Ibn Umm Maktum as a ruler of Madinah, and entrusted the banner of war to ‘Ali bin Abi Talib who marched towards the appointed target and came close enough to hear the Jews abusing the Messenger of Allâh [pbuh], who on his part set out at the head of three thousand infantry men and thirty horsemen of Ansar (Helpers) and Muhajireen (Emigrants). On their way to encounter the enemy, the afternoon prayer was due. Some Muslims refused to observe it until they had defeated the enemy, while others offered it in its proper time, as usual. The Prophet [pbuh] objected to neither. When they reached the habitations of Banu Quraiza, they laid tight siege to their forts. Seeing this terrible situation they were in, the chief of the Jews Ka‘b bin Asad offered them three alternatives: to embrace Islam, and consequently their life, wealth, women and children would be in full security, and reminded them that such behaviour would not be incongruous with what they had read in their books about the veracity of Muhammad’s Prophethood; to kill their children and women and then challenge the Prophet [pbuh] and his followers to the sword to either exterminate the Muslims or be exterminated, or as a third possibility to take Muhammad [pbuh] and his people by surprise on Saturday — a day mutually understood to witness no fighting.
None of those alternatives appealed them, so their chief, angrily and indignantly, turned to them saying: "You have never been decisive in decision-making since you were born" The gloomy future already visible, they made contacts with some Muslims, who had maintained good relation with them, in order to learn about their fate in the light of the current circumstances. They requested that Abu Lubaba be despatched to them for advice. On his arrival, the men began to implore, women and children to cry desperately. In answer to their demand for advice he pointed to his throat saying it was homicide awaiting them. He then immediately realized that he had betrayed the Prophet’s trust, so he headed directly for the mosque in Madinah and tied himself to a wooden tall pole swearing that no one would untie him save the Messenger of Allâh [pbuh], and added that he would never enter the habitation of Banu Quraiza in recompense for the deadly mistake he made. When the Messenger [pbuh] was informed of this incident, he said, " I would have begged Allâh to forgive him if he had asked me, but since he had tied himself out of his own free will, then it was Allâh Who would turn to him in forgiveness."
The Jews of Banu Quraiza could have endured the siege much longer because food and water were plentifully available and their strongholds were greatly fortified, whereas the Muslims were in the wild bare land suffering a lot from cold and hunger, let alone too much fatigue consequent on endless warfare operations that had started even before the battle of Confederates. Nevertheless, this was a battle of nerves, for Allâh had cast fear in the the Jews’ hearts, and their morale had almost collapsed especially when two Muslim heroes, ‘Ali bin Abi Talib and Az-Zubair bin
