Jami` at-Tirmidhi 1915
Aishah said:
"A woman came to me with two daughters. She was asking (for food) but I did not have anything with me except a date. So I gave it to her and she divided it between  her two daughters without eating any of it herself. Then she got up to leave, and the Prophet entered, and I informed him about her. So the Prophet said: " Whoever is tested something from these daughters (and he/she passes the test), they will be a screen for them from the Fire."
حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدٍ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ الْمُبَارَكِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ ابْنِ شِهَابٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ أَبِي بَكْرِ بْنِ حَزْمٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ دَخَلَتِ امْرَأَةٌ مَعَهَا ابْنَتَانِ لَهَا فَسَأَلَتْ فَلَمْ تَجِدْ عِنْدِي شَيْئًا غَيْرَ تَمْرَةٍ فَأَعْطَيْتُهَا إِيَّاهَا فَقَسَمَتْهَا بَيْنَ ابْنَتَيْهَا وَلَمْ تَأْكُلْ مِنْهَا ثُمَّ قَامَتْ فَخَرَجَتْ فَدَخَلَ النَّبِيُّ صلى الله عليه وسلم فَأَخْبَرْتُهُ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏
"‏ مَنِ ابْتُلِيَ بِشَيْءٍ مِنْ هَذِهِ الْبَنَاتِ كُنَّ لَهُ سِتْرًا مِنَ النَّارِ ‏"‏ ‏.‏ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏
