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."  

عَنْ زَيْنَبَ ابْنَةِ جَحْشٍ ؓن أَنَّهَا قَالَتِ اسْتَيْقَظَ النَّبِيُّ ﷺ 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  

Once the Prophet ﷺ stood over one of the high buildings of Medina and then said (to the people), "Do you see what I see?" They said, "No." He said, "I see afflictions falling among your houses as rain drops fall."  

أَشْرَفَ النَّبِيُّ ﷺ عَلَى أُطُمٍ مِنْ آطَامِ الْمَدِينَةِ فَقَالَ هَلْ تَرَوْنَ مَا أَرَى قَالُوا لاَ قَالَ فَإِنِّي لأَرَى الْفِتَنَ تَقَعُ خِلاَلَ بُيُوتِكُمْ كَوَقْعِ الْقَطْرِ
