"The black people came and played in front of the Prophet ﷺ on the day of 'Eid. He called me and I watched them from over his shoulder, and I continued to watch them until I was the one who moved away." (Using translation from Nasāʾī 1594)  

«جَاءَ السُّودَانُ يَلْعَبُونَ بَيْنَ يَدَيِ النَّبِيِّ ﷺ فِي يَوْمِ عِيدٍ فَدَعَانِي وَكُنْتُ أَطَّلِعُ إِلَيْهِمْ مِنْ فَوْقِ عَاتِقِهِ فَمَا زِلْتُ أَنْظُرُ إِلَيْهِمْ حَتَّى كُنْتُ أَنَا الَّتِي انْصَرَفْتُ»  

[Machine] The Messenger of Allah ﷺ said, "Leave them, O Umar, for they are the sons of Arfidah."  

رَسُولُ اللهِ ﷺ «دَعْهُمْ يَا عُمَرُ فَإِنَّمَا يَعْنِي هُمْ بَنُو أَرْفِدَةَ»
