Chapter : The merit of according benevolent treatment to daughters.
'Aisha, the wife of Allah's Apostle (may peace be upon him), said: A woman came to me along with her two daughters. She asked me for (charity) but she found nothing with me except one date, so I gave her that. She accepted it and then divided it between her two daughters and herself ate nothing out of that. She then got up and went out, and so did her two daughters. (In the meanwhile) Allah's Apostle (may peace be upon him) visited me and I narrated to him her story. Thereupon Allah's Apostle (may peace be upon him) said: He who is involved (in the responsibility) of (bringing up) daughters, and he accords benevolent treatment towards them, there would be protection for him against Hell-Fire.
