Sahih Muslim Book 54, Hadith 7
" When I met Abu Ja'far I told him that she (simply) meant the plain ground. Thereupon Abu Ja'far said: No, by God, she meant the plain ground of Medina.
Allah's Messenger, what about him who would be made to accompany this army willy nilly? Thereupon he said: He would be made to sink along with them but he would be raised on the Day of Resurrection on the basis of his intention. Abu Ja'far said. ' This plain, ground means the plain ground of Medina.
An army would attack this House in order to fight against the inhabitants of this House and when it would be at the plain ground the ranks in the centre of the army would be sunk and the vanguard would call the rear flanks of the army and they would also be sunk and no flank would be left except some people who would go to inform them (their kith and kin). A person (who had been listening to this hadith from Abdullah b. Safwan) said: I bear testimony in regard to you that you are not imputing a lie to Hafsa. And I bear testimony to the fact that Hafsa is not telling a lie about Allah's Apostle (ﷺ).
