السادس: عَنْ أُمِّ الْمُؤْمِنِينَ أُمِّ الحكم زينب بنت جحش رَضِيَ اللَّه عَنْهَا أَنَّ النَّبِيَّ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ دَخَلَ عَلَيْهَا فَزِعًا يَقُولُ: "لاَ إِلَهَ إِلاَّ اللَّهُ، وَيْلٌ لِلْعَرَبِ مِنْ شَرٍّ قَدِ اقْتَرَبَ، فُتِحَ الْيَوْمَ مِنْ رَدْمِ يَأْجُوجَ وَمَأْجُوجَ مِثْلُ هَذِهِ” وَحَلَّقَ بأصبعيه الإِبْهَامِ وَالَّتِي تَلِيهَا. فَقُلْتُ: يَا رَسُولَ اللَّهِ أَنَهْلِكُ وَفِينَا الصَّالِحُونَ؟ قَالَ: "نَعَمْ إِذَا كَثُرَ الْخَبَثُ" ((مُتَّفَقٌ عَلَيْهِ)) .
Zainab (May Allah be pleased with her) reported: The Prophet (ﷺ) came to visit me one day frightened and he (ﷺ) said: "La ilaha illallah (There is no true God but Allah). Woe to the Arabs because of an evil which has drawn near! Today an opening of this size has been made in the barrier restraining Ya'juj and Ma'juj (Gog and Magog people)." And he (ﷺ) made a circle with his thumb and index finger. I said, "O Messenger of Allah! Shall we perish while still there will be righteous people among us?'' He (ﷺ) replied, "Yes, when wickedness prevails". [Al-Bukhari and Muslim].
