It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "A fire will emerge from Hadramaut (which is a region of Syria) and will drive the people forward." We asked: O Messenger of Allah! What do you command us to do at that time? He said: "Make the land of Syria obligatory upon yourselves (go there)."
