What is the religious ruling on the punishment for incest (zina al-mahārim), and is it permissible after repentance for the person to be alone with the one with whom they committed incest, or to sit with her in front of everyone, and is the kinship between them severed?

Adultery is a grave sin, forbidden and even more prohibited if committed with a mahram (unmarriageable kin). Whoever commits this abomination must offer sincere repentance, characterized by remorse, abstaining from the sin, and resolving never to return to it. They should also strive to associate with righteous individuals, fulfill their religious obligations, and perform many supererogatory acts of worship. Private seclusion and looking at mahrams with whom adultery was committed are forbidden after the act, but the kinship between them remains.
