What reward will a person's mother receive if they give alms on her behalf after her death, according to the teachings of Prophet Muhammad (saw)?
 Narrated Aisha:                     A man said to the Prophet (p.b.u.h), "My mother died suddenly and I thought that if she had lived she would have given alms. So, if I give alms now on her behalf, will she get the reward?" The Prophet replied in the affirmative.
