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.
