Expiation for complaining about one's parents after their death

Question:
Another person says: I was young and my father was 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 so on. They have since passed away, and I regret it deeply. Is there an expiation for that?

Answer:
Yes, yes. You must repent to Allah and regret what you did with your parents. This means that you regret what has passed, and that you 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 after that. You should guard your tongue regarding them, except by making du'a' for them, seeking forgiveness for them, sending blessings upon them, and being kind to them by giving charity on their behalf and the like, to the extent you are able. And beware of returning to what Allah has forbidden for you, for repentance wipes out what came before it, and praise be to Allah. Yes.
