Ibn 'Umar reported Messenger of Allah ﷺ as saying: You will fight against the Jews and you will kill them until even a stone would say: Come here, Muslim, there is a Jew (hiding himself behind me); kill him.

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ، حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ ﷺ قَالَ " لَتُقَاتِلُنَّ الْيَهُودَ فَلَتَقْتُلُنَّهُمْ حَتَّى يَقُولَ الْحَجَرُ يَا مُسْلِمُ هَذَا يَهُودِيٌّ فَتَعَالَ فَاقْتُلْهُ "
