How can one redress moral and material injustices to their rightful owners when it is impossible to reach them or they have died, and how is this done in the case of wronging parents, and what are the consequences for someone who dies with an injustice against them on the Day of Judgment?

"Injustices that do not involve the rights of human beings can only be absolved by fulfilling the conditions of repentance. However, if the injustice relates to the right of another person, then it is stipulated that the injustice be returned to its rightful owner, or that absolution be obtained from them. Injustices that occur between one person and another are either intangible, in which case, deliverance from them comes through seeking forgiveness from the person wronged during their lifetime, or they are tangible, in which case it is necessary to return the right to them or to seek forgiveness and pardon from them. It is essential to strive to return tangible injustices to their rightful owners or seek their absolution, whether they are alive, by returning the right to them, or deceased, by returning it to their heirs. If you are unable to do so, then you must increase your acts of seeking forgiveness, performing righteous deeds, and giving charity on their behalf in proportion to the injustice. You must return what you stole from your father or mother to them by any means you are able to after repenting, seeking forgiveness, and resolving not to return to it again. The one who dies while you have an injustice against them will not take all your good deeds on the Day of Resurrection, but rather will take from them in proportion to the injustice.
