بَاب لَا تَقُومُ السَّاعَةُ حَتَّى يَمُرَّ الرَّجُلُ بِقَبْرِ الرَّجُلِ فَيَتَمَنَّى أَنْ يَكُونَ مَكَانَ الْمَيِّتِ مِنْ الْبَلَاءِ
Sahih Muslim 2909 c

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

It would be an Abyssinian having two small shanks who would destroy the House ol Allah, the Exalted and Glorious.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، - يَعْنِي الدَّرَاوَرْدِيَّ - عَنْ ثَوْرِ بْنِ، زَيْدٍ عَنْ أَبِي الْغَيْثِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ ذُو السُّوَيْقَتَيْنِ مِنَ الْحَبَشَةِ يُخَرِّبُ بَيْتَ اللَّهِ عَزَّ وَجَلَّ ‏"‏ ‏.‏
