Sahih Bukhari Volume 2, Book 24, Hadith 1419

حَدَّثَنَا بِشْرُ بْنُ مُحَمَّدٍ، قَالَ أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، قَالَ حَدَّثَنِي عَبْدُ اللَّهِ بْنُ أَبِي بَكْرِ بْنِ حَزْمٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ دَخَلَتِ امْرَأَةٌ مَعَهَا ابْنَتَانِ لَهَا تَسْأَلُ، فَلَمْ تَجِدْ عِنْدِي شَيْئًا غَيْرَ تَمْرَةٍ فَأَعْطَيْتُهَا إِيَّاهَا، فَقَسَمَتْهَا بَيْنَ ابْنَتَيْهَا وَلَمْ تَأْكُلْ مِنْهَا، ثُمَّ قَامَتْ فَخَرَجَتْ، فَدَخَلَ النَّبِيُّ صلى الله عليه وسلم عَلَيْنَا، فَأَخْبَرْتُهُ فَقَالَ ‏"‏ مَنِ ابْتُلِيَ مِنْ هَذِهِ الْبَنَاتِ بِشَىْءٍ كُنَّ لَهُ سِتْرًا مِنَ النَّارِ ‏"‏‏

Narrated By 'Aisha : A lady along with her two daughters came to me asking (for some alms), but she found nothing with me except one date which I gave to her and she divided it between her two daughters, and did not eat anything herself, and then she got up and went away. Then the Prophet came in and I informed him about this story. He said, "Whoever is put to trial by these daughters and he treats them generously (with benevolence) then these daughters will act as a shield for him from Hell-Fire."
