Sahih al-Bukhari 1494
Narrated Um 'Atiyya Al-Ansariya:
The Prophet (ﷺ) went to `Aisha and asked her whether she had something (to eat). She replied that she 
had nothing except the mutton (piece) which Nusaiba (Um 'Atiyya) had sent to us (Barira) in 
charity." The Prophet (ﷺ) said, "It has reached its place and now it is not a thing of charity but a gift for 
us."
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، حَدَّثَنَا خَالِدٌ، عَنْ حَفْصَةَ بِنْتِ سِيرِينَ، عَنْ أُمِّ عَطِيَّةَ الأَنْصَارِيَّةِ ـ رضى الله عنها ـ قَالَتْ دَخَلَ النَّبِيُّ صلى الله عليه وسلم عَلَى عَائِشَةَ ـ رضى الله عنها ـ فَقَالَ ‏"‏ هَلْ عِنْدَكُمْ شَىْءٌ ‏"‏‏.‏ فَقَالَتْ لاَ‏.‏ إِلاَّ شَىْءٌ بَعَثَتْ بِهِ إِلَيْنَا نُسَيْبَةُ مِنَ الشَّاةِ الَّتِي بَعَثْتَ بِهَا مِنَ الصَّدَقَةِ‏.‏ فَقَالَ ‏"‏ إِنَّهَا قَدْ بَلَغَتْ مَحِلَّهَا ‏"‏‏.‏
