Revival Sunnah

‘Aa’ishah (may Allaah be pleased with her) reported that a man said to the Prophet (peace and blessings of Allaah be upon him): "My mother has passed away, and if she could have spoken, she would have given something in charity. Will she receive a reward if I give something on her behalf?" He said, "Yes." (Reported by al- Bukhaari, Fath, 1388)
