The Book of Virtue, Enjoining Good Manners, and Joining of the Ties of Kinship
Ṣaḥīḥ Muslim 6694
إِنَّ اللَّهَ قَدْ أَوْجَبَ لَهَا بِهَا الْجَنَّةَ أَوْ أَعْتَقَهَا بِهَا مِنَ النَّارِ
inna-Llāh qad awjaba lahā bihā al-jannaha aw aʿtaqahā bihā mina an-nāri

The full narration
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
