Is it permissible for a daughter to fast on behalf of her deceased mother as a make-up for missed Ramadan fasts?

If someone dies and owes fasts, and they were unable to make them up due to an illness that led to their death, then there is nothing upon them. However, if they were able to make them up but neglected to do so, scholars differ: Some are of the opinion that the fasts should be observed on their behalf, based on the hadith of Aisha (may Allah be pleased with her): "Whoever dies and owes fasts, their guardian should fast on their behalf." Others are of the opinion that food should be given as expiation for each day, approximately one "mudd" of food (about 750 grams).
