Is it considered falsely accusing someone of adultery (qadhf) if a man says: I saw a man enter the home of so-and-so’s wife in his absence?

Question:
He says: Honorable Shaykh, may Allah grant you success, if a person sees someone enter the home of another person’s wife and informs the woman’s husband, is this considered falsely accusing someone of adultery (qadhf)?

Answer:
No, this is not considered such an accusation until he says that he committed adultery with her or that she committed adultery, using the word for adultery. As for merely entering, that is an accusation; it is considered an accusation, not falsely accusing someone of adultery (qadhf). Yes.
