Riyad as-Salihin

'Aishah (May Allah be pleased with her) reported: A poor woman came to me carrying her two daughters. I gave her three date-fruits. She gave a date to each of them and then she took up one date-fruit and brought that to her mouth to eat, but her daughters asked her that also. She then divided between them the date-fruit that she intended to eat. This (kind) treatment of her impressed me and I mentioned that to Messenger of Allah (ﷺ) who said, 'Verily, Allah has assured Jannah for her, because of (this act) of her," or said, "He (SWT) has rescued her from Hell- Fire".
