What is "dhul-suwayqatayn"

Dhul-Suwayqatayn ( Arabic: ذوالسويقتين) is a group that prophecies by Muhammad say will emerge at the end of time. They are Abyssinian ( Ethiopian) men destined by Allah to destroy the Kabah. There are two traditions regarding the time of the Kabaa's destruction:

• The Kaaba will be destroyed when Isa is still alive. Before Isa's army can reach him, Allah sends a wind to take the souls of all believers, leaving only disbelievers behind. Dhul-Suwayqatayn will then destroy the Kaabah, taking it down brick by brick.
• The Kaaba will be destroyed after Yajuj and Majuj perish from the Earth and Isa has died while Muslims still perform Hajj and Umrah. As quoted by a hadith narrated by Abu Sa`id al-Khudri saying that Muslims will still be doing Hajj & Umrah to Kabaa after the event of Yajuj and Majuj.
