What is the ruling on going to a woman who claims to know the unseen through cards? And is it permissible to tell one's mother about that?

Repentance erases sin, and one who repents from sin is like one who has no sin. Therefore, the sister who asked the question should repent with sincere repentance and not return to this act. She should forbid evil and not obey anyone in a matter that angers Allah. She should explain to her friends that only Allah knows the unseen, and whoever claims to know it is a charlatan. She should conceal herself and not inform her mother.
