Compiled by Imam Muslim ibn al-Hajjaj
حَدَّثَنَا عَمْرُو بْنُ سَوَّادٍ الْعَامِرِيُّ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، أَخْبَرَنِي عَمْرُو بْنُ، الْحَارِثِ أَنَّ بَكْرَ بْنَ سَوَادَةَ، حَدَّثَهُ أَنَّ يَزِيدَ بْنَ رَبَاحٍ - هُوَ أَبُو فِرَاسٍ مَوْلَى عَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ - حَدَّثَهُ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُ قَالَ " إِذَا فُتِحَتْ عَلَيْكُمْ فَارِسُ وَالرُّومُ أَىُّ قَوْمٍ أَنْتُمْ " . قَالَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ نَقُولُ كَمَا أَمَرَنَا اللَّهُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَوْ غَيْرَ ذَلِكَ تَتَنَافَسُونَ ثُمَّ تَتَحَاسَدُونَ ثُمَّ تَتَدَابَرُونَ ثُمَّ تَتَبَاغَضُونَ أَوْ نَحْوَ ذَلِكَ ثُمَّ تَنْطَلِقُونَ فِي مَسَاكِينِ الْمُهَاجِرِينَ فَتَجْعَلُونَ بَعْضَهُمْ عَلَى رِقَابِ بَعْضٍ " .
How would you be, O people, when Persia and Rome would be conquered for you? `Abd ar-Rahman b `Auf said: We would say as Allah has commanded us and we would express our gratitude to Allah. Thereupon Allah's Messenger (ﷺ) said: Nothing else besides it? You would (in fact) vie with one another, then you would feel jealous, then your relations would be estranged and then you will bear enmity against one another, or something to the same effect. Then you would go to the poor emigrants and would make some the masters of the others.
