Zainab bint Jahsh reported that Allah's Apostle ﷺ got up from sleep saying: There is no god but Allah;
there is a destruction in store for Arabia because of turmoil which is at hand, the barrier of Gog and Magog has opened so much. And Sufyan made a sign of ten with the help of his hand (in order to indicate the width of the gap) and I said: Allah's Messenger, would we be perished in spite of the fact that there would be good people amongst us? Thereupon he said: Of course, but only when the evil predominates.

حَدَّثَنَا عَمْرٌو النَّاقِدُ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ زَيْنَبَ، بِنْتِ أُمِّ سَلَمَةَ عَنْ أُمِّ حَبِيبَةَ، عَنْ زَيْنَبَ بِنْتِ جَحْشٍ، أَنَّ النَّبِيَّ ﷺ اسْتَيْقَظَ مِنْ نَوْمِهِ وَهُوَ يَقُولُ " لاَ إِلَهَ إِلاَّ اللَّهُ وَيْلٌ لِلْعَرَبِ مِنْ شَرٍّ قَدِ اقْتَرَبَ فُتِحَ الْيَوْمَ مِنْ رَدْمِ يَأْجُوجَ وَمَأْجُوجَ مِثْلُ هَذِهِ " . وَعَقَدَ سُفْيَانُ بِيَدِهِ عَشَرَةً . قُلْتُ يَا رَسُولَ اللَّهِ أَنَهْلِكُ وَفِينَا الصَّالِحُونَ قَالَ " نَعَمْ إِذَا كَثُرَ الْخَبَثُ " .
