Narrated from Sayyida Zainab bint Jahsh (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) woke up from sleep, while his face was red, and he was saying: "There is no god but Allah. Woe to the Arabs because of the evil that has drawn near. Today, a hole as big as this has been opened in the wall of Gog and Magog." And he (peace and blessings be upon him) made a circle with his fingers to show it. I said: "O Messenger of Allah! Will we be destroyed while there are righteous people among us?" He (peace and blessings be upon him) said: "Yes, when evil becomes widespread."
