It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "O Allah, bless us in our Sham; O Allah, bless us in our Yemen." He (peace and blessings be upon him) said this several times, and on the third or fourth time the people said: O Messenger of Allah, and in our Iraq too? He (peace and blessings be upon him) said: "There will be earthquakes and tribulations there, and from there the horn of Satan will emerge."
