Zainab bint Jahsh said:
One day the Messenger of Allah(s.a.w) awoke from sleep with a flushed red face, and said: 'La Ilahaillallah. He repeated it thrice. 'Woe to the Arabs from the evil drawn near. Today a gap has been made in the wall of Ya'juj and Ma'juj like this.' And he formed ten(with his fingers). Zainab said: I said: 'O Messenger of Allah! Shall we be destroyed while they are righteous among us?' He said: 'Yes, when the evil abounds. '
