Sahih Muslim , Book 41, Hadith 6981 (USC-MSA) ⓘ
Ibn 'Umar reported Allah's Messenger 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 صلى الله عليه وسلم قَالَ " لَتُقَاتِلُنَّ الْيَهُودَ فَلَتَقْتُلُنَّهُمْ حَتَّى يَقُولَ الْحَجَرُ يَا مُسْلِمُ هَذَا يَهُودِيٌّ فَتَعَالَ فَاقْتُلْهُ " .
