Sahih al-Bukhari · Book 56: Fighting for the Cause of Allah (Jihaad) · Fighting against the Jews
Narrated `Abdullah bin `Umar:
حَدَّثَنَا إِسْحَاقُ بْنُ مُحَمَّدٍ الْفَرْوِيُّ ، حَدَّثَنَا مَالِكٌ ، عَنْ نَافِعٍ ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " تُقَاتِلُونَ الْيَهُودَ حَتَّى يَخْتَبِيَ أَحَدُهُمْ وَرَاءَ الْحَجَرِ فَيَقُولُ يَا عَبْدَ اللَّهِ هَذَا يَهُودِيٌّ وَرَائِي فَاقْتُلْهُ " .
Allah's Messenger (ﷺ) said, "You (i.e. Muslims) will fight with the Jews until some of them will hide behind stones. The stones will (betray them) saying, 'O `Abdullah (i.e. slave of Allah)! There is a Jew hiding behind me; so kill him.'"
