Is a woman who repents from adultery considered "muhsanah" (chaste/protected by marriage) after her repentance, and is insulting her considered "qadhf" (slanderous accusation of unchastity) against chaste women?

Adultery is one of the major sins that incurs Allah's wrath, but sincere repentance erases this sin. If an adulteress repents, the description of adultery is removed from her, as the Prophet, peace and blessings be upon him, said: "The one who repents from a sin is like one who has no sin." True repentance restores a chaste person's chastity, for one is considered chaste and free from adultery outwardly, even if they were repentant from it.
