Is the testimony of two witnesses valid if they testify that someone committed *qadhf* (slander concerning chastity) against them, after admitting enmity?

Primary text

The testimony of two witnesses testifying that a person committed *qadhf* against them is not accepted because they admitted enmity towards the accused, and the testimony of an enemy against their enemy is invalid. If they subsequently pardon the accused, thus removing the enmity, and then testify to the same *qadhf*, their testimony remains invalid. This is analogous to a wicked person (*fasīq*) whose testimony is rejected due to their wickedness, and whose subsequent repentance does not immediately reinstate their testimony upon retrial.
