Sahih Muslim 2630
'A'isha reported:
A poor woman came to me along with her daughters. I gave her three dates. She gave a date to each of them and then she took up one date and brought that to her mouth in order to eat that, but her daughters expressed desire to eat it. She then divided the date that she intended to eat between them. This (kind) treatment of her impressed me and I mentioned that which she did to Allah's Messenger (ﷺ). Thereupon he said: Verily Allah has assured Paradise for her, because of (this act) of her, or He has rescued her from Hell-Fire.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا بَكْرٌ، - يَعْنِي ابْنَ مُضَرَ - عَنِ ابْنِ الْهَادِ، أَنَّ زِيَادَ،
 بْنَ أَبِي زِيَادٍ مَوْلَى ابْنِ عَيَّاشٍ حَدَّثَهُ عَنْ عِرَاكِ بْنِ مَالِكٍ، سَمِعْتُهُ يُحَدِّثُ، عُمَرَ بْنَ عَبْدِ الْعَزِيزِ
 عَنْ عَائِشَةَ، أَنَّهَا قَالَتْ جَاءَتْنِي مِسْكِينَةٌ تَحْمِلُ ابْنَتَيْنِ لَهَا فَأَطْعَمْتُهَا ثَلاَثَ تَمَرَاتٍ فَأَعْطَتْ
 كُلَّ وَاحِدَةٍ مِنْهُمَا تَمْرَةً وَرَفَعَتْ إِلَى فِيهَا تَمْرَةً لِتَأْكُلَهَا فَاسْتَطْعَمَتْهَا ابْنَتَاهَا فَشَقَّتِ التَّمْرَةَ
 الَّتِي كَانَتْ تُرِيدُ أَنْ تَأْكُلَهَا بَيْنَهُمَا فَأَعْجَبَنِي شَأْنُهَا فَذَكَرْتُ الَّذِي صَنَعَتْ لِرَسُولِ اللَّهِ صلى
 الله عليه وسلم فَقَالَ ‏
"‏ إِنَّ اللَّهَ قَدْ أَوْجَبَ لَهَا بِهَا الْجَنَّةَ أَوْ أَعْتَقَهَا بِهَا مِنَ النَّارِ ‏"‏ ‏.‏
