According to two narrations in Sahih Bukhari, Muhammad asks Allah to bless the areas of Sham and Yemen. When his companions said "Our Najd as well," he replied: "There will appear earthquakes and afflictions, and from there will come out the side of the head (e.g. horns) of Satan." In a similar narration, Muhammad again asked Allah to bless the areas Medina, Mecca, Sham, and Yemen and, when asked specifically to bless Najd, repeated similar comments about there being earthquakes, trials, tribulations, and the horns of Satan.
"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 their appears the Horn of Satan."
"A people that recite Qur'an will come out of the East (East of Arabia, Riyad), but it will not go past their throats. They will pass through the religion (of Islam) like the arrow passes through its quarry. They will no more come back to the religion than the arrow will come back to its course. Their sign is that they shave (their heads)."
"At the end of times a man will come out of Musaylima's country and he will change the religion of Islam."
