The ruling on a man saying, "This child is not mine," and whether this counts as falsely accusing someone of zina

The questioner:
He says: Honorable Shaykh, may Allah grant you success, regarding the statement of the author (may Allah have mercy on him): "The man says, but this child is not mine." The question is: How is this not an accusation of adultery (qadhf), when he has disavowed the child, and this is an accusation that it is from another?

The Shaykh:
My brother, what is an accusation of adultery? This could be a case where she was coerced or forced, or that she was impregnated by the fluid of another. An accusation of adultery must be explicit, with no room for any other possibility.

The questioner:
It becomes a valid claim.

The Shaykh:
A person should reflect before asking, so as not to burden himself with the question. Merely denying paternity does not imply an accusation of adultery, because she may have been coerced, or she may have been impregnated by another's fluid, or there may be other possibilities.
