What is the authenticity of the hadith: "A band from my Ummah will conquer the White House, the house of Khosrow"?

This Hadith is authentic, narrated by Muslim in his Sahih, from Amir bin Saad bin Abi Waqas who said: I wrote to Jabir bin Samurah asking him to inform me of something he heard from the Messenger of Allah (peace and blessings of Allah be upon him). So he wrote to him: I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "The religion will continue to be upright until the Hour comes, or there will be twelve Caliphs, all of them from Quraysh." And I heard him say: "A small group of Muslims will conquer the White House, the house of Kisra or the family of Kisra." And I heard him say: "Indeed, before the Hour there will be liars, so beware of them." And I heard him say: "If Allah gives one of you good, let him begin with himself and his family." And I heard him say: "I am the foremost at the Hawd (Pool)."
