Fasting on behalf of the deceased as Kaffarah for manslaughter

Q: Before his death, my father suffered from many diseases. He also had a car accident in Riyadh - Al-Qasim road where three people died. The report of the accident indicated that my father was responsible for the accident. He survived the accident suffering illnesses for five years. These diseases, especially diabetes, prevented him from fasting the days required for Kaffarah (expiation). He finally suffered from paralysis resulting in his death. (Part No. 21; Page No. 326) We are ten children, females and males, and want to make up the missed fasts required by Kaffarah according to Shari`ah. Please advise. May Allah protect you from every evil and harm.

A: Among the acts of showing gratitude to your father is making up for the fasts required by the Kaffarah that your father owed before his death, as the Prophet (peace be upon him) said, Whoever dies owing fasts, his heir should fast on his behalf. This act is good and desirable. It is noteworthy that the Kaffarah of involuntary manslaughter for each one killed by your father is to fast for two consecutive months (sixty days). Additionally, it is impermissible for more than one person to share the fasts required by one Kaffarah, but rather each one should observe one Kaffarah.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
