How would you be, O people, when Persia and Rome would be conquered for you? ʿAbd ar-Rahman b ʿAuf said: We would say as Allah has commanded us and we would express our gratitude to Allah. Thereupon Messenger of Allah 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.
عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ إِذَا فُتِحَتْ عَلَيْكُمْ فَارِسُ وَالرُّومُ أَىُّ قَوْمٍ أَنْتُمْ قَالَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ نَقُولُ كَمَا أَمَرَنَا اللَّهُ قَالَ رَسُولُ اللَّهِ ﷺ أَوْ غَيْرَ ذَلِكَ تَتَنَافَسُونَ ثُمَّ تَتَحَاسَدُونَ ثُمَّ تَتَدَابَرُونَ ثُمَّ تَتَبَاغَضُونَ أَوْ نَحْوَ ذَلِكَ ثُمَّ تَنْطَلِقُونَ فِي مَسَاكِينِ الْمُهَاجِرِينَ فَتَجْعَلُونَ بَعْضَهُمْ عَلَى رِقَابِ بَعْضٍ
