Sahih Muslim 2883 a
Abdullah b. Safwan reported that Hafsa told him that she had heard Allah's Apostle (ﷺ) as saying:
An army would attack this House in order to fight against the inhabitants of this House and when it would be at the plain ground the ranks in the centre of the army would be sunk and the vanguard would call the rear flanks of the army and they would also be sunk and no flank would be left except some people who would go to inform them (their kith and kin). A person (who had been listening to this hadith from Abdullah b. Safwan) said: I bear testimony in regard to you that you are not imputing a lie to Hafsa. And I bear testimony to the fact that Hafsa is not telling a lie about Allah's Apostle (ﷺ).
حَدَّثَنَا عَمْرٌو النَّاقِدُ، وَابْنُ أَبِي عُمَرَ، - وَاللَّفْظُ لِعَمْرٍو - قَالاَ حَدَّثَنَا سُفْيَانُ بْنُ،
 عُيَيْنَةَ عَنْ أُمَيَّةَ بْنِ صَفْوَانَ، سَمِعَ جَدَّهُ عَبْدَ اللَّهِ بْنَ صَفْوَانَ، يَقُولُ أَخْبَرَتْنِي حَفْصَةُ، أَنَّهَا سَمِعَتِ 
 النَّبِيَّ صلى الله عليه وسلم يَقُولُ ‏
"‏ لَيَؤُمَّنَّ هَذَا الْبَيْتَ جَيْشٌ يَغْزُونَهُ حَتَّى إِذَا كَانُوا بِبَيْدَاءَ
 مِنَ الأَرْضِ يُخْسَفُ بِأَوْسَطِهِمْ وَيُنَادِي أَوَّلُهُمْ آخِرَهُمْ ثُمَّ يُخْسَفُ بِهِمْ فَلاَ يَبْقَى إِلاَّ الشَّرِيدُ
 الَّذِي يُخْبِرُ عَنْهُمْ ‏"‏ ‏.‏ فَقَالَ رَجُلٌ أَشْهَدُ عَلَيْكَ أَنَّكَ لَمْ تَكْذِبْ عَلَى حَفْصَةَ وَأَشْهَدُ عَلَى حَفْصَةَ
 أَنَّهَا لَمْ تَكْذِبْ عَلَى النَّبِيِّ صلى الله عليه وسلم
