That one day Messenger of Allah ﷺ entered upon her in a state of fear and said, "None has the right to be worshipped but Allah! Woe to the Arabs from the Great evil that has approached (them). Today a hole has been opened in the dam of Gog and Magog like this." The Prophet ﷺ made a circle with his index finger and thumb. Zainab bint Jahsh added: I said, "O Alllah's Apostle! Shall we be destroyed though there will be righteous people among us?" The Prophet ﷺ said, "Yes, if the (number) of evil (persons) increased."
أَنَّ رَسُولَ اللَّهِ ﷺ دَخَلَ عَلَيْهَا يَوْمًا فَزِعًا يَقُولُ لاَ إِلَهَ إِلاَّ اللَّهُ وَيْلٌ لِلْعَرَبِ مِنْ شَرٍّ قَدِ اقْتَرَبَ فُتِحَ الْيَوْمَ مِنْ رَدْمِ يَأْجُوجَ وَمَأْجُوجَ مِثْلُ هَذِهِ وَحَلَّقَ بِإِصْبَعَيْهِ الإِبْهَامِ وَالَّتِي تَلِيهَا قَالَتْ زَيْنَبُ ابْنَةُ جَحْشٍ فَقُلْتُ يَا رَسُولَ اللَّهِ أَفَنَهْلِكُ وَفِينَا الصَّالِحُونَ قَالَ نَعَمْ إِذَا كَثُرَ الْخُبْثُ
