The ruling on a mother fasting on behalf of her son as expiation for accidental killing

Question:
Abu Abdullah from Taif, please, Abu Abdullah. Peace be upon you, and Allah's mercy and blessings. And upon you peace. Camera. And Allah's mercy and blessings, please proceed. I have two questions, O Abu Qilah, the Shaykh. Please proceed. My first question is that I have a son who was involved in an accident and died; the accident happened to him and his brother's son, and then he relinquished everything, and the fasting—he did not complete the twenty days; his mother fasted two months on his behalf. Does this suffice or not? Good, the Shaykh will answer.

Answer:
If he was of legal age, if he was of legal age and liable for the accident, then fasting on his behalf does not suffice unless he is unable to do so due to a permanent inability, in which case fasting on his behalf suffices. However, as long as he is capable of fasting and has reached legal age, it is obligatory for him to fast. But if he dies and he has fasting to make up, then his guardian fasts on his behalf. But as long as he is alive and capable of fasting, it is obligatory for him to do so. Yes.
