عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ دَخَلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ الْمَسْجِدَ وَالْحَبَشَةُ يَلْعَبُونَ فَزَجَرَهُمْ عُمَرُ رَضِيَ اللَّهُ عَنْهُ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ”دَعْهُمْ يَا عُمَرُ فَإِنَّهُمْ بَنُو أَرْفِدَةَ“
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) entered the mosque, where some Abyssinians were playing with spears. Sayyiduna Umar (may Allah be pleased with him) scolded them. But the Noble Prophet (peace and blessings be upon him) said: Umar! Leave them, they are Banu Arfidah, (meaning this is among their customs).
