What did the Prophet Muhammad (peace be upon him) say when his followers asked him to bless their Najd, in addition to their Sham and Yemen?
 Narrated Ibn `Umar:                     (The Prophet) said, "O Allah! Bless our Sham and our Yemen." People said, "Our Najd as well." The Prophet again said, "O Allah! Bless our Sham and Yemen." They said again, "Our Najd as well." On that the Prophet said, "There will appear earthquakes and afflictions, and from there will come out the side of the head of Satan."
