Is it permissible to perform the prayer and fasting on behalf of the deceased, and does this apply only to the sick person whom illness prevented from praying, or does it include every deceased person who missed prayers without an excuse, and one who originally abandoned prayer? What is the مقدار (amount) of expiation for prayer and fasting, and is it permissible to give its monetary value instead of feeding, and what is its current amount?

If a person breaks their fast in Ramadan and then dies before recovering, there is nothing due from them. However, if they recover and are able to make up the fasts but do not do so until they die, then the fasts are due from them. It is not permissible for the guardian to fast on behalf of the deceased. Instead, food should be given to one needy person for each day, because fasting is a strenuous act of worship for the body that cannot be performed by a proxy. The expiation (fidya) is to be taken from one-third of their wealth if they made a will to that effect. If the deceased was able to make up the fasts, then it is permissible for someone to fast on their behalf according to many scholars. According to some, feeding the poor is obligatory. For each day, one mudd of food (approximately 750 grams) should be given. The monetary value is not sufficient according to the majority of scholars, but it is permissible according to the Hanafis and those who believe it serves the interest of the poor.
