Expiation for Fasting, Oaths, and Zihar for the Deceased

Question:
May Allah reward you, Honorable Shaykh. If a person dies and he has an expiation for fasting and prayer, is it permissible for another person to perform it on his behalf by providing an expiation from money, grains, and barley?

Answer:
Yes. If the deceased has an expiation due to him—whether for fasting, for an oath, or for zihar—and if it is possible to free a slave from his estate, then a slave is freed on his behalf. If that is not possible, then food is given on his behalf: ten poor people are fed for the oath, and sixty poor people are fed for zihar. And if he had fasting due to him.
I mean, first, the expiation—for example, the expiation for intercourse in Ramadan—is in a specific order, like the expiation for zihar. First, so his guardian performs this act. If he is able to free a slave, he frees one on his behalf. If he is not able to free a slave, he fasts on his behalf. If he is not able to fast, he feeds sixty poor people on his behalf. This is for the expiation of zihar and intercourse in Ramadan. As for the expiation for an oath, it is a matter of choice: if he wishes, he frees a slave on his behalf; if he wishes, he feeds ten poor people on his behalf; and if he wishes, he clothes ten poor people, giving each poor person a garment, by choice. If he does not have any of these things, he fasts three days on his behalf. Likewise, fasting in the expiation for zihar, in the expiation for killing, and in a vow—if he vowed to fast—his guardian fasts on his behalf, based on the saying of the Messenger (peace and blessings be upon him): And in a narration: “Whoever fasts and has a vowed fast due to him, his guardian fasts on his behalf.” Yes.
