'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)'."

وَقَالَتْ عَائِشَةُ رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم يَسْتُرُنِي، وَأَنَا أَنْظُرُ إِلَى الْحَبَشَةِ وَهُمْ يَلْعَبُونَ فِي الْمَسْجِدِ، فَزَجَرَهُمْ عُمَرُ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ دَعْهُمْ، أَمْنًا بَنِي أَرْفِدَةَ ‏"‏‏.‏ يَعْنِي مِنَ الأَمْنِ‏

Narrated By Ibn 'Abbas : The Prophet went out and offered a two Rakat prayer on the Day of 'Id-ul-Fitr and did not offer any other prayer before or after it and at that time Bilal was accompanying him.

حَدَّثَنَا أَبُو الْوَلِيدِ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ حَدَّثَنِي عَدِيُّ بْنُ ثَابِتٍ، قَالَ سَمِعْتُ سَعِيدَ بْنَ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم خَرَجَ يَوْمَ الْفِطْرِ، فَصَلَّى رَكْعَتَيْنِ لَمْ يُصَلِّ قَبْلَهَا وَلاَ بَعْدَهَا وَمَعَهُ بِلاَلٌ‏
