Narrated by Ibn ‘Umar

The Prophet said, “O Allah! Bestow Your blessings on our Sham! O Allah! Bestow Your blessings on our Yemen.” The People said, “And also on our Najd.” He said, “O Allah! Bestow Your blessings on our Sham (north)! O Allah! Bestow Your blessings on our Yemen.” The people said, “O Allah’s Apostle! And also on our Najd.” I think the third time the Prophet said, “There (in Najd) is the place of earthquakes and afflictions and from there comes out the side of the head of Satan.”
