Sahih al-Bukhari 7059
Narrated Zainab bint Jahsh:
The Prophet (ﷺ) got up from his sleep with a flushed red face and said, "None has the right to be 
worshipped but Allah. Woe to the Arabs, from the Great evil that is nearly approaching them. Today a 
gap has been made in the wall of Gog and Magog like this." (Sufyan illustrated by this forming the 
number 90 or 100 with his fingers.) It was asked, "Shall we be destroyed though there are righteous 
people among us?" The Prophet (ﷺ) said, "Yes, if evil increased."
حَدَّثَنَا مَالِكُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا ابْنُ عُيَيْنَةَ، أَنَّهُ سَمِعَ الزُّهْرِيَّ، عَنْ عُرْوَةَ، عَنْ زَيْنَبَ بِنْتِ أُمِّ سَلَمَةَ، عَنْ أُمِّ حَبِيبَةَ، عَنْ زَيْنَبَ ابْنَةِ جَحْشٍ ـ رضى الله عنهن ـ أَنَّهَا قَالَتِ اسْتَيْقَظَ النَّبِيُّ صلى الله عليه وسلم مِنَ النَّوْمِ مُحْمَرًّا وَجْهُهُ يَقُولُ ‏"‏ لاَ إِلَهَ إِلاَّ اللَّهُ، وَيْلٌ لِلْعَرَبِ مِنْ شَرٍّ قَدِ اقْتَرَبَ، فُتِحَ الْيَوْمَ مِنْ رَدْمِ يَاجُوجَ وَمَاجُوجَ مِثْلُ هَذِهِ ‏"‏‏.‏ وَعَقَدَ سُفْيَانُ تِسْعِينَ أَوْ مِائَةً‏.‏ قِيلَ أَنَهْلِكُ وَفِينَا الصَّالِحُونَ قَالَ ‏"‏ نَعَمْ، إِذَا كَثُرَ الْخَبَثُ ‏"‏‏.‏
