The ruling on the fidyah (ransom payment) for the errors of a deceased pilgrim

Question:
May Allah reward you. This questioner, whose name was indicated by the letters alif and waw, says: My father performed Hajj last year. He was advanced in age and ignorant of many of the rulings of Hajj. The following errors occurred on his part: First, he did not perform the farewell tawaf (circumambulation) due to his ignorance. This is the first point. Second, he did not shave or shorten his hair. Third, he stoned the three pillars on all three days of Tashriq in the morning, not after the sun passed its zenith, due to his ignorance. The question is: Is his Hajj valid? And what do we do now that he has passed away to the mercy of Allah?

Answer:
His Hajj is valid, if Allah wills. He must offer a fidyah (ransom payment) for these matters. First, regarding the farewell tawaf, a fidyah is required of him. If he left an estate, the fidyah is paid from his estate. If he did not leave an estate, and one of his relatives or others wishes to do him a favor and fulfill his obligation by slaughtering the fidyah for him in Makkah and distributing it to the poor, that is good. Likewise, stoning the pillars before their proper time on the days of Tashriq does not require slaughtering; instead, a fidyah is offered in its place. If he has an estate, it is paid from his estate. Otherwise, if one of his relatives or others volunteers to slaughter the fidyah for him for stoning the pillars, that is a good thing, but the slaughter must be in Makkah. The slaughter must be in Makkah and distributed to the poor. As for shaving or shortening the hair, this is the omission of an obligatory act of Hajj, so a third fidyah is also required of him in place of the shaving or shortening.
