How to make up for
    disobedience towards parents after they have died
Question

                If a person was disobedient towards his
      parents, and they died angry with him, how can he put things right so that they will not
      ask him to put it right in the Hereafter?
Praise be to Allah.There is no way to stop them asking him to put things
    right in the Hereafter, but now that he has felt regret for what he did, he should make
    lots of du;aa; for them and ask Allaah to forgive them, give charity on their behalf if he
    can, honour the friends etc, whom they loved, uphold their ties of kinship, pay off their
    debts and do whatever else he can.
