Sahih Muslim 2922
Sahih Muslim · Book 54: The Book of Tribulations and Portents of the Last Hour · The Hour Will Not Begin Until A Man Passes By Another Man's Grave And Wishes That He Was In The Place Of The Deceased, Because Of Calamity
Abu Huraira reported Allah's Messenger (ﷺ) as saying:
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 " .
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.
