It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that he said: "Among the last events concerning the Ka'bah is that the Abyssinians will attack the House (of Allah), and the Muslims will set out towards them. Then Allah Almighty will send upon them a wind from the east, and Allah Almighty will not leave any servant in whose heart there is even the weight of a speck of piety except that He will take his soul, until, when they have been emptied of their good people, only the rabble will remain, who will neither enjoin good nor forbid evil. Every tribe will return to the idols that their forefathers used to worship and will begin worshipping them, until they will copulate in the streets just as animals do. Then the Hour will be established upon them. So whoever informs you of anything after this has no knowledge of it." This hadith has an authentic (sahih) chain of narration on the condition of the two Shaykhs (Bukhari and Muslim), but it is mawquf (a Companion's own statement).
