يَكُونُ فِي آخِرِ الزَّمَانِ أَقْوَامٌ إِخْوَانُ الْعَلَانِيَةِ، وَأَعْدَاءُ السَّرِيرَةِ، فَقِيلَ: يَا رَسُولَ اللَّهِ، وَكَيْفَ يَكُونُ ذَلِكَ؟ قَالَ: ذَلِكَ بِرَغْبَةِ بَعْضِهِمْ إِلَى بَعْضٍ، وَرَهْبَةِ بَعْضِهِمْ مِنْ بَعْضٍ
Translation: Toward the end of time there will be people who appear as brothers in public but harbor hostility privately. Asked how that could happen, the Prophet ﷺ explained that some will seek things from others while others will fear them.

إِخْوَانُ الْعَلَانِيَةِ refers to outward brotherliness, while أَعْدَاءُ السَّرِيرَةِ describes private hostility. رَغْبَةٌ is desire for a benefit, and رَهْبَةٌ is fear.
The report cautions against relationships governed by gain or intimidation rather than sincerity. Ordinary courtesy or disagreement is not itself proof of hidden hostility; conduct and the protection of others’ rights matter.
