On sadaqa and supplication for the deceased

Riyad as-Salihin (The Meadows of the Righteous)

by Imam Nawawi

162. Chapter: On sadaqa and supplication for the deceased

Allah Almighty says, "Those who have come after them say, 'Our Lord, forgive us and our brothers who preceded us in belief.'" (59:10)

948. 'A'isha reported that a man said to the Prophet, may Allah bless him and grant him peace, "My mother died, and I think that if she had spoken, she would have given sadaqa. Will she have a reward if I give sadaqa on her behalf?" He said, "Yes." [Agreed upon]

949. Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "When a man dies, his actions are cut off except for three – an on-going sadaqa and knowledge which brought benefit and a virtuous son who makes supplication for him." [Muslim]
