{{Main|Battle of Khaybar}}

Abu Bakr took part in the [[Battle of Khaybar]]. Khaybar had eight fortresses, the strongest and most well-guarded of which was called Al-Qamus. Muhammad sent Abu Bakr with a group of warriors to attempt to take it, but they were unable to do so. Muhammad also sent Umar with a group of warriors, but Umar could not conquer Al-Qamus either.<ref>{{cite book |last1=Razwy |first1=Sayed Ali Asgher |title=A Restatement of the History of Islam & Muslims |page=192}}</ref><ref>{{cite book |last1=Ibn Ishaq |title=The Life of the Messenger of God}}</ref><ref name="The Life of Mohammed">{{cite book |last1=Irving |first1=Washington |title=The Life of Mohammed}}</ref><ref>{{cite book |last1=Haykal |first1=Muhammad Husayn |title=The Life of Muhammad |date=1935 |quote=As the days went by, the Prophet sent Abu Bakr with a contingent and a flag to the fortress of Na'im; but he was not able to conquer it despite heavy fighting.
