"O Allaah bestow your blessings on our Shaam. O Allaah bestow your blessings on our Yemen." The people said, "O Messenger of Allaah, and our Najd." I think the third time the Prophet, sallallaahu alayhi wa sallam, said, "There (in Najd) will occur earthquakes, trials and tribulations, and from there appears the Horn of Satan."
