GOG AND MAGOG H H 190 "One day the Prophet, praise and peace be upon him, entered in great concern and said: 'There is no god except Allah. Woe to the Arabs from the evil which is approaching. A breach this size has been made in the wall that holds back Gog and Magog;' and he made a circle between his thumb and forefinger. I (Lady Zainab) said to him: 'O Messenger of Allah, praise and peace be upon him, shall we be destroyed when there are a number of the righteous among us?' He replied: 'Yes, when evil becomes widespread.'" R 190 Bukhari and Muslim with a chain up to Lady Zainab wife of the Prophet, may Allah be pleased with her, Mother of Believers who related this.
189- السادس : عن أم المؤمنين أم الحكم زينب بنتِ جحش رَضِي الله عنها : أن النَّبيّ صلى الله عليه وآله وسلم دخل عَلَيْهَا فَزِعاً ، يقول : "لا إلهَ إلاّ الله ، وَيلٌ للْعَرَبِ مِنْ شَرٍّ قَدِ اقْتَرَبَ ، فُتِحَ اليَوْمَ مِنْ رَدْمِ يَأجُوجَ وَمَأجُوجَ مِثلَ هذِهِ" ، وحلّق بأُصبُعيهِ الإبهامِ والتي تليها ، فقلتُ : يَا رَسُول الله ، أنَهْلِكُ وَفِينَا الصَّالِحُونَ ؟ قَالَ : "نَعَمْ ، إِذَا كَثُرَ الخَبَثُ" مُتَّفَقٌ عَلَيهِ .
