Suffering from cancer severely during Ramadan and breaking Sawm

Q: My mother suffered from cancer, and the disease became so severe on 13 Ramadan, 1411 A.H., causing her to break Sawm (Fast). She remained ill until she died on 11 Shawwal, 1411 A.H. I do not know whether I should observe Sawm and give Kaffarah (expiation) on her behalf. Please advise.

A: If the case is as you mentioned, there is nothing upon the mother because she is excused for breaking her Sawm. Moreover, she was not able to make up for these days until she died.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
