Narrated to me Harmalah ibn Yahya: Ibn Wahb informed us: Yunus informed me, from Ibn Shihab, who said: Urwah ibn al-Zubayr informed me that Zaynab bint Abi Salamah told him that Umm Habibah bint Abi Sufyan told her that Zaynab bint Jahsh, the wife of the Prophet, peace and blessings be upon him, said: The Messenger of Allah, peace and blessings be upon him, went out one day alarmed, his face flushed, saying: "There is no god but Allah. Woe to the Arabs from an evil that has drawn near. Today a gap has been opened in the wall of Gog and Magog like this" — and he formed a circle with his thumb and the finger next to it. She said: I said, "O Messenger of Allah, shall we be destroyed while there are righteous people among us?" He said: "Yes, when wickedness becomes prevalent."
