After that he called some persons of Bani Sulaym, Asba, Raal and Zakwan for help, who surrounded the Muslims from all sides. Muslims drew their swords and fought with them and were finally killed. Kaab bin Zaid was seriously wounded and was lying among the dead. They thought that he was dead, so he escaped alive. He was martyred in the Battle of Khandaq. And Amr bin Umayyah Zumri and an Ansari had taken all the camels belonging to Muslims to graze them and they were unaware of this incident.
When they returned, they found Muslims lying in blood and dust. Ansari asked Amr, “What should be done?” He replied: “I will go to the Prophet.” “I will not leave the place where Manzar bin Amr was martyred,” and he drew the sword and fought them till he was also martyred. And Amr was taken as a prisoner by the idolaters. When they came to know that he was from the tribe of Zumar, they didn’t eliminate him. They said: My mother was supposed to free a slave, so I release him in lieu.
Thus Amr came to the Prophet and narrated the incident. The Messenger of Allah (S) was much aggrieved by this and he blamed Abu Baraa. Hassan bin Thabit and Kaab bin Malik composed poems to condemn the oath breaking of Abu Baraa. When Abu Baraa came to know about it, he was so infuriated that he died because of it. And Rabia, son of Abu Baraa, to compensate for the oath breaking of his father, attacked Aamir with a dagger, but he turned on the horse and was not killed.
According to a report, the following verse was also revealed which was not included in Qur’an: “That is convey to my people the message that we have met our Lord in such condition that He was pleased with us and we were pleased with Him.” Battle of Bani Nuzayr: Shaykh Tabarsi, Ali bin Ibrahim and Ibn Shahr Ashob etc.
have narrated that when the Messenger of Allah (S) migrated to Medina, the Jew tribe of Bani Nuzayr who were the best people of Medina had made a treaty of perfect neutrality with the Prophet on his first arrival at Medina.
