It is narrated from Sayyiduna Abdullah bin Unays (may Allah be pleased with him) that the party whom the Messenger of Allah (peace and blessings be upon him) sent to Abdullah bin Abi al-Huqayq (the Jew) to kill him were Abdullah bin Atik, Abdullah bin Unays, Abu Qatadah (may Allah be pleased with them), an ally of theirs and a man from the Ansar. They reached Khaybar at night. (Abdullah bin Unays relates:) We went to the doors of their houses and shut them from the outside. The wife of Ibn Abi al-Huqayq said: This is the voice of Abdullah bin Atik. He said: Open the door. So she opened it, and Abdullah bin Atik and I went in. Abdullah said: Deal with her (hold her back). I was about to strike her with the sword when I remembered the prohibition of the Messenger of Allah (peace and blessings be upon him) against killing women and children, so I held back from her.
Ali bin al-Madini said: This is Abdullah bin Unays al-Ansari, not al-Juhani; this is the Abdullah bin Unays al-Ansari from whom Jabir bin Abdullah (may Allah be pleased with them both) narrated.
