Zainab bint Jahsh reported that Allah's Apostle (ﷺ) got up from sleep saying
There is no being worthy of worship except Allah; there is a destruction in store for Arabia because of turmoil which is at hand, the barrier of Gog and Magog has opened so much. And Sufyan made a sign of ten with the help of his hand (in order to indicate the width of the gap) and I said: Allah's Messenger, would we be perished in spite of the fact that there would be good people amongst us? Thereupon he said: Of course, but only when the evil predominates.
This hadith has been narrated on the authority of Zainab bint Jahsh with a slight variation in the chain of transmitters.
Zainab bint Jahsh, the wife of Allah's Apostle (ﷺ), reported that one day Allah's Messenger (ﷺ) came out in a state of excitement with his face quite red. And he was saying
There is no god but Allah; there is a destruction in store for Arabia because of the turmoil which is near at hand as the barrier of Gog and Magog has been opened like it, and he (in order to explain it) made a ring with the help of his thumb and forefinger. I said: Allah's Messenger, would we be destroyed despite the fact that there would be pious people amongst us? He said: Yes, when evil would be predominant.
This hadith has been narrated on the authority of Zuhri with a different chain of transmitters.
Abu Huraira reported Allah's Apostle (ﷺ) as saying
Today the wall (barrier) of Gog and Magog has been opened so much, and Wuhaib (in order to explain it) made the figure of ninety with the help of his hand.
