It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Even after the emergence of Gog and Magog, Hajj and 'Umrah to this House (the Ka'bah) will certainly be performed." In the narration of Abu Qudamah, it is stated that after Gog and Magog, Hajj and 'Umrah will continue to be performed. And in the narration of Abu Musa, it is stated that Hajj to this House will certainly be performed.
