عَنْ سَهْلِ بْنِ حُنَيْفٍ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّهُ قَالَ ((مَنْ أُذِلَّ عِنْدَهُ مُؤْمِنٌ فَلَمْ يَنْصُرْهُ وَهُوَ قَادِرٌ عَلَى أَنْ يَنْصُرَهُ أَذَلَّهُ اللَّهُ عَزَّ وَجَلَّ عَلَى رُءُوسِ الْخَلَائِقِ يَوْمَ الْقِيَامَةِ))
It is narrated from Sayyiduna Sahl bin Hunaif (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever, in whose presence a believer is humiliated and he does not help him, while he is able to help, then Allah Almighty will humiliate him before all of creation on the Day of Resurrection.
