Expiation for complaining about one's parents after their death

Question:
Another person says: I was young and my parents were with me, and I often got annoyed by their interference in my affairs and in the matters between me and my children, and I would complain about that and other things. They have since passed away, and I regret it deeply. Is there an expiation for what happened?

Answer:
Yes, yes. You must repent to Allah and regret what you did with your parents. This means that you should regret the bad behavior that came from you, and you should stop, after their death, from speaking in ways that would upset them, or talking about things that would upset them, or mentioning any of their faults. You should guard your tongue regarding them, except by making du'a' (supplication) for them, seeking forgiveness for them, sending blessings upon them, and being kind to them by giving charity on their behalf and doing similar things. Beware of returning to what Allah has forbidden for you, for repentance wipes out what came before it, and praise be to Allah. Yes.
