Abdullah Ibn Buraydah reported his father as saying, that he was sitting with the Prophet (SAW) when a woman arrived. She submitted, “0 Messenger of Allah! I had given a female slave to my mother as zakah, and she has died’. He said, “Your reward is due to you while she (slave) is returned to you as your inheritance”. She said, “0 Messenger of Allah! Fasting of a month was due on my mother, may I fast on her behalf?” He said, “Keep fast for her”. She asked, ‘0 Messenger of Allah! She had not performed hajj at all; may I perform hajj for her?” He said, “Yes. Make the pilrimage on her behalf”.
