وَعَنِ ابْنِ عُمَرَ - رَضِيَ اَللَّهُ عَنْهُمَا- قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ اَلْعَرَبُ بَعْضُهُمْ أَكْفَاءُ بَعْضٍ , وَالْمَوَالِي بَعْضُهُمْ أَكْفَاءُ بَعْضٍ , إِلَّا حَائِكٌ أَوْ حَجَّامٌ } رَوَاهُ اَلْحَاكِمُ , وَفِي إِسْنَادِهِ رَاوٍ لَمْ يُسَمَّ , وَاسْتَنْكَرَهُ أَبُو حَاتِمٍ [1] .
Narrated Ibn 'Umar (RA): Allah's Messenger (ﷺ) said: "The Arabs are equal to one another and the Mawali (Non-Arabs, and originally former slaves) are equal to one another, except a weaver or a cupper." [Reported by al-Hakim, but there is a nameless narrator in its chain of narration; Abu Hatim graded it Munkar (rejected)].
