question #3 Sahih Muslim 1004a, Book 12, Hadith 63 : How does intention play a role in the reward of charitable acts done on behalf of someone else?

My mother died suddenly without having made any will. I think she would have definitely given Sadaqa if she had been able to speak. Would she have a reward if I gave Sadaqa on her behalf? He (the Holy Prophet) said: Yes.
