Mukhtasar Muslim

´Sayyiduna Jabir bin Samurah رضي الله عنه says that` I heard the Messenger of Allah صلى الله عليه وسلم say: Certainly, a group of Muslims or believers (the narrator is unsure) will open the treasury of Kisra, which is in the white palace. In Qutaibah’s narration, it is “Muslims” without any doubt.
