Musannaf Ibn Abi Shayba 37:212

Abu Amir al-Aqadi narrated to us, from Ali ibn al-Mubarak, from Yahya, who said: Abu Qilabah narrated to me, who said: Salim ibn Abdullah narrated to me, who said: Abdullah ibn Umar narrated to me, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "A fire will emerge before the Day of Resurrection from the sea of Hadhramaut, gathering the people." They said: "O Messenger of Allah, what do you command us?" He said: "You must go to Ash-Sham."
