Sunan Ibn Majah 3953

It was narrated that Zainab bint Jahsh said:“The Messenger of Allah (ﷺ) woke up red in the face and said: ‘La ilaha illallah, woe to the Arabs from an evil that has drawn nigh. Today a hole has been opened in the barrier of Gog and Magog.’ And he gestured to indicate the size of the hole.” Zainab said: “I said: ‘O Messenger of Allah! Will we be destroyed when there are righteous people among us?’ He said: ‘If sin and evil deeds increase.’”
