Chapter: The virtue of spending and giving charity to relatives, spuses, children and parents, even if they are idolaters
Umm Salama said: I asked the Messenger of Allah ( صلی اللہ علیہ وسلم ) whether there is a reward for me if I spend on Abu Salama's sons, and I am not going to abandon them in this state (of helplessness) for they are my sons. He (the Holy Prophet) said: Yes. For you is the reward for what you spend on them.
