I heard the Messenger of Allah ﷺ say, "A band of Muslims, or of believers, will surely conquer the treasure of the family of Kisra that lies in the White Palace."
سمعت رسول الله ﷺ يقول: لتفتحن عصابة من المسلمين- أو من المؤمنين- كنز آل كسرى الذي في الأبيض.
Muslim narrated it in the Book of Tribulations (78:2919) from Qutayba bin Saeed and Abu Kamil Jahdari, who both said, "Abu Awana narrated to us from Simak bin Harb, from Jabir bin Samura," and he mentioned it.Imam Muslim said, Qutayba said, "from the Muslims," without any doubt.
