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
