Hadith 1274:4
Ya'qub narrated to us, my father narrated to us, from Ibn Ishaq, who said: Ibn Shihab mentioned, from 'Urwah ibn al-Zubayr, from Zaynab bint Abi Salamah, from Umm Habibah bint Abi Sufyan, from Zaynab bint Jahsh, who said: The Messenger of Allah, peace and blessings of Allah be upon him, entered upon me while he was joining his index finger with his thumb, and he was saying: "Woe to the Arabs from an evil that has drawn near. Today, a hole has been opened in the barrier of Gog and Magog like the size of this," and he made a circle with his two fingers. She said: I said: "O Messenger of Allah, shall we perish while there are righteous people among us?" He, peace and blessings of Allah be upon him, said: "Yes, if wickedness increases."
حدثنا يعقوب، حدثنا أبي، عن ابن إسحاق، قال: ذكر ابن شهاب، عن عروة بن الزبير، عن زينب بنت أبي سلمة، عن أم حبيبة بنت أبي سفيان، عن زينب بنت جحش، قالت: دخل علي رسول الله صلى الله عليه وسلم وهو عاقد بأصبعيه السبابة بالإبهام وهو يقول: " ويل للعرب من شر قد اقترب فتح اليوم من ردم يأجوج، ومأجوج مثل موضع الدرهم " قالت: فقلت: يا رسول الله أنهلك وفينا الصالحون؟ قال صلى الله عليه وسلم: " نعم إذا كثر الخبث "
