"A woman came to the Holy Prophet (May Allah bless him and give him peace) and said, 'I have given charity on behalf of my dead mother by giving away her female servant.' The Holy Prophet answered, 'You will have its reward [and so will she] but return the female servant so that the inheritance [may be properly divided].' The woman then said, 'She used to owe fasts, can I fast on her behalf' He answered, 'You may fast on her behalf.' The woman then said, 'She did not perform Hajj, can I perform on her behalf' The Holy Prophet answered, 'Yes. You may perform Hajj on her behalf." (Tirmizi)
