I heard Messenger of Allah ﷺ as saying: There would lie open for a group of Muslims, or for a group of believers, the treasures of the family of Kisra which would be in the white (palace). In a version of Qutaiba there is definitely the word "Muslim". (Using translation from Muslim 2919b)   

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ لَتَفْتَحَنَّ عِصَابَةٌ مِنَ الْمُسْلِمِينَ أَوْ مِنَ الْمُؤْمِنِينَ كَنْزَ آلِ كِسْرَى الَّذِي فِي الْأَبْيَضِ  

[Machine] I heard the Prophet ﷺ saying, "A group of Muslims will conquer the white palace of the Kisra family."  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ لَتَفْتَحَنَّ عِصَابَةٌ مِنَ الْمُسْلِمِينَ أَبْيَضَ آلِ كِسْرَى  

[Machine] I heard the Messenger of Allah ﷺ saying, "Some of the Muslims give shelter to others."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ يُجِيرُ عَلَى الْمُسْلِمِينَ بَعْضُهُمْ  

[Machine] I heard the Messenger of Allah ﷺ saying: "You will surely conquer the treasures of Kisra Al-Abiad, or the treasures within it, with a group of Muslims."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «لَتَفْتَحَنَّ لَكُمْ كُنُوزَ كِسْرَى الْأَبْيَضَ أَوِ الَّذِي فِي الْأَبْيَضِ عِصَابَةٌ مِنَ الْمُسْلِمِينَ»  

[Machine] I heard the Messenger of Allah ﷺ saying, "A party of Muslims will conquer the white palace of Caesar."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «لَيَفْتَحَنَّ أَبْيَضَ آلِ كِسْرَى عِصَابَةٌ مِنَ الْمُسْلِمِينَ»
