Sunan an-Nasa'i 2880
Hafsah narrated that he said:
An invading army will come toward this House until when they are in Al-Baida, the middle of them will be swallowed up by the earth. The first of them will call out to the last of them, and they will be wallowed up, until there is no one left of them except a fugitive who will tell of what happened to them." 
A man (hearing the narration) said: "I bear witness that you did not attribute a lie to your grandfather, and I bear witness that your grandfather did not attribute a lie to Hafsah, and I bear witness that Hafsh, did not attribute a lie to the Prophet.
أَخْبَرَنَا الْحُسَيْنُ بْنُ عِيسَى، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ أُمَيَّةَ بْنِ صَفْوَانَ بْنِ عَبْدِ اللَّهِ بْنِ صَفْوَانَ، سَمِعَ جَدَّهُ، يَقُولُ حَدَّثَتْنِي حَفْصَةُ، أَنَّهُ قَالَ صلى الله عليه وسلم ‏
"‏ لَيَؤُمَّنَّ هَذَا الْبَيْتَ جَيْشٌ يَغْزُونَهُ حَتَّى إِذَا كَانُوا بِبَيْدَاءَ مِنَ الأَرْضِ خُسِفَ بِأَوْسَطِهِمْ فَيُنَادِي أَوَّلُهُمْ وَآخِرُهُمْ فَيُخْسَفُ بِهِمْ جَمِيعًا وَلاَ يَنْجُو إِلاَّ الشَّرِيدُ الَّذِي يُخْبِرُ عَنْهُمْ ‏"‏ ‏.‏ فَقَالَ لَهُ رَجُلٌ أَشْهَدُ عَلَيْكَ أَنَّكَ مَا كَذَبْتَ عَلَى جَدِّكَ وَأَشْهَدُ عَلَى جَدِّكَ أَنَّهُ مَا كَذَبَ عَلَى حَفْصَةَ وَأَشْهَدُ عَلَى حَفْصَةَ أَنَّهَا لَمْ تَكْذِبْ عَلَى النَّبِيِّ صلى الله عليه وسلم ‏.‏
