Abu Huraira reported Allah's Messenger (ﷺ) as saying:

The last hour would not come unless the Muslims will fight against the Jews and the Muslims would kill them until the Jews would hide themselves behind a stone or a tree and a stone or a tree would say: Muslim, or the servant of Allah, there is a Jew behind me; come and kill him; but the tree Gharqad would not say, for it is the tree of the Jews.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا يَعْقُوبُ، - يَعْنِي ابْنَ عَبْدِ الرَّحْمَنِ - عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ لاَ تَقُومُ السَّاعَةُ حَتَّى يُقَاتِلَ الْمُسْلِمُونَ الْيَهُودَ فَيَقْتُلُهُمُ الْمُسْلِمُونَ حَتَّى يَخْتَبِئَ الْيَهُودِيُّ مِنْ وَرَاءِ الْحَجَرِ وَالشَّجَرِ فَيَقُولُ الْحَجَرُ أَوِ الشَّجَرُ يَا مُسْلِمُ يَا عَبْدَ اللَّهِ هَذَا يَهُودِيٌّ خَلْفِي فَتَعَالَ فَاقْتُلْهُ ‏.‏ إِلاَّ الْغَرْقَدَ فَإِنَّهُ مِنْ شَجَرِ الْيَهُودِ ‏"‏ ‏.‏
