Musnad Ahmad 1153:2042

Rawh narrated to us, he said: Muhammad ibn Abi Hafsah narrated to us, from Ibn Shihab, from Ibn Hazm, from Urwah, from Aisha, who said: A woman entered upon me with two daughters of hers, so I fed her a date. She split it between them and did not eat anything from it herself. Then the Messenger of Allah, peace and blessings of Allah be upon him, entered upon me, and I mentioned that to him. He said: "Whoever is tested with anything regarding daughters, and treats them well, they will be a shield for him from the Fire."
