The ruling on one who is unable to fast as expiation for accidental killing, and whether it is permissible for someone else to fast on his behalf?

Question:
We move on to a message from one of our brother listeners in the Kingdom of Saudi Arabia. He says: I am a young man, twenty years old, and I am not married. I was employed in one of the cities of the Kingdom. I took leave from my work and traveled to my family by car. Four of my colleagues were with me, and I was driving the car. It was in the last part of Ramadan. I was driving at a speed of about one hundred kilometers per hour, and a technical malfunction occurred in my car, which caused an accident. All four of my colleagues died. Now I am at my job, far from my family, and I am unable to fast. My mother wants to fast two months on my behalf. Is it permissible for her to do this fasting? And is there an expiation other than fasting?

Answer:
If it has been determined by the court that you are responsible for the blood of those who died in the accident, even if it is only a small percentage of the accident. If you are responsible for twenty percent or five percent of the accident, then you owe the expiation for every soul that died in this accident. The expiation, as Allah the Exalted mentioned, is freeing a slave. If , and you remember that you are unable to fast due to your circumstances, and that your mother wants to fast some of the expiations on your behalf, this is not sufficient. Rather, the expiation remains a debt in your obligation until you are able to fast, and then you will fast, with the permission of Allah, in the future.
Also, it is not necessary to continue the expiations one after the other without a break. Rather, you fast, for example, the expiation of two months, then you rest for a period, then you fast the second expiation of two consecutive months, then you rest, then you fast the third expiation, and so on. It is not necessary to continue the expiations one after the other in fasting, because this is difficult for you. But you fast whatever is easy for you, and when you complete it, you rest for some time, then you start the second one until you complete it, and so on until Allah the Exalted helps you to clear your obligation. Yes.
