Al-Huqayq was succeeded by Usayr ibn Zarim. It has been recorded by one source that Usayr also approached the Ghatafan and rumors spread that he intended to attack the "capital of Muhammad". The latter sent Abdullah bin Rawaha with a number of his companions, among whom was Abdullah bin Unays, an ally of Banu Salima, a clan hostile to the Jews. When they came to Usayr, they told him that if he would come to Muhammad, Muhammad would give him an appointment and honour him. They kept on at him until he went with them with a number of Jews. Abdullah bin Unays mounted him on his beast until he was in al-Qarqara, about six miles from Khaybar. Usayr suddenly changed his mind about going with them. Abdullah perceived Usayr's bad intention as the latter was preparing to draw his sword. So Abdullah rushed at him and struck him with his sword cutting off his leg. Usayr hit Abdullah with a stick of shauhat wood which he had in his hand and wounded his head. All Muhammad's emissaries fell upon the thirty Jewish companions and killed them except one man who escaped on his feet. Abdullah bin Unays is the assassin who volunteered and got permission to kill Banu Nadir's Sallam ibn Abu al-Huqayq at a previous night mission in Khaybar.
