Hadith ~ An army will invade the Ka'ba

'A'isha, Umm al-Mu'minin, Umm 'Abdullah said, "The Messenger of Allah, may Allah bless him and grant him peace, said, 'An army will invade the Ka'ba. When they are at Bayda', the earth will swallow them up from the first to the last of them.'" She said, "I said, 'Messenger of Allah, how will it swallow them up from the first to the last of them when their traders are among them as well as others who are not really part of them?' He said, 'It will swallow them up from the first to the last of them and then they will resurrected according to their intentions.'" [Agreed upon. This is the version in al-Bukhari.]
