Abdullah bin Buraidah narrated from his father: "I was sitting with the Prophet when a woman came to him and said: 'O Messenger of Allah! I gave a slave girl to my mother in charity and she died.' He said: 'Your reward is already established, and your right to inherit her has returned it (that Sadaqah) to you.' She said: 'O Messenger of Allah! There was a month of fasting due on her, shall I perform the fast for her?' He said: 'Fast on her behalf.' She said: 'O Messenger of Allah! She never performed Hajj, shall I perform Hajj for her?' He said: 'Yes, perform Hajj on her behalf.'"
