وَقَالَتْ عَائِشَةُ : رَأَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَسْتُرُنِي وَأَنَا أَنْظُرُ إِلَى الْحَبَشَةِ وَهُمْ يَلْعَبُونَ فِي الْمَسْجِدِ فَزَجَرَهُمْ عُمَرُ ، فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : دَعْهُمْ أَمْنًا بَنِي أَرْفِدَةَ يَعْنِي مِنَ الْأَمْنِ " .
`Aisha further said, "Once the Prophet was screening me and I was watching the display of black slaves in the Mosque and (`Umar) scolded them. The Prophet said, 'Leave them. O Bani Arfida! (carry on), you are safe (protected)'."
