Is it obligatory to perform Hajj on behalf of the deceased who was capable of it but did not perform it, and is there a sin incurred for that?

Scholars have differed regarding one who negligently neglects Hajj despite being able to perform it. Some have permitted performing Hajj on their behalf, while others have prohibited it. The most authoritative opinion is that it is not valid, because one who abandons the obligatory Hajj without an excuse is not absolved of their responsibility by having Hajj performed on their behalf after their death. As for Zakat, it is disbursed from the estate because it is a right of the poor, but it does not absolve the owner who did not pay Zakat, and they will be punished for it. Regarding fasting, if one neglects it out of negligence without a legitimate Shar'i excuse, it is not to be made up for them. The saying of the Prophet (peace be upon him): (Whoever dies with fasts due upon them, their guardian should fast on their behalf) applies to one who did not neglect making up the fasts.
