Sahih al-Bukhari · Book 92: Afflictions and the End of the World · To seek refuge with Allah from Al-Fitan
وَقَالَ عَبَّاسٌ النَّرْسِيُّ حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ ، حَدَّثَنَا سَعِيدٌ ، حَدَّثَنَا قَتَادَةُ ، أَنَّ أَنَسًا ، حَدَّثَهُمْ أَنَّ نَبِيَّ اللَّهِ صلى الله عليه وسلم بِهَذَا وَقَالَ كُلُّ رَجُلٍ لاَفًّا رَأْسَهُ فِي ثَوْبِهِ يَبْكِي. وَقَالَ عَائِذًا بِاللَّهِ مِنْ سُوءِ الْفِتَنِ. أَوْ قَالَ أَعُوذُ بِاللَّهِ مِنْ سُوءِ الْفِتَنِ.
The the above hadith was narrated by Anas through another chain and said (with the wording) "and every man had his head wrapped in his garment and weeping". And he said (with the wording) "seeking refuge with Allah from the evil of afflictions" or he said "I seek refuge with Allah from the evil of afflictions."
