Buraida said that when he was sitting with the Prophet a woman came to him and said,“Messenger of God, I gave a slavegirl as sadaqa to my mother who has now died.”He replied.“Your reward is sure, and the inheritance has given her back to you.”She said, "Messenger of God, a month's fast was due from her; may I fast on her behalf ?”He replied,“Fast on her behalf.”She said,“She never performed the pilgrimage, so may I do so on her behalf ?”He replied,“Yes, perform the pilgrimage on her behalf.”Muslim transmitted it.
