Salim bin Abdullah narrates from his father (Sayyiduna Abdullah bin Umar, may Allah be pleased with them both) that the Prophet Muhammad (peace and blessings be upon him) said: "In the last era, a fire will emerge from Hadramaut that will gather the people together." The narrator says: We asked, "O Messenger of Allah! What do you command us to do then?" The Prophet Muhammad (peace and blessings be upon him) said: "Stay in Sham (Greater Syria)."
(Imam Ibn Hibban, may Allah have mercy on him, says:) The beginning of Sham is Balis and its end is Arish of Egypt.
