Claiming the knowledge of the Ghayb is Kufr (disbelief). Allah (Exalted be He) says:
Say: “None in the heavens and the earth knows the Ghaib (Unseen) except Allâh”
This woman must change her name to something more acceptable, such as
`Aishah, and the like until she is no longer known for claiming the Ghayb. Moreover, she should repent sincerely to Allah for claiming the knowledge of the Ghayb and practicing forbidden soothsaying and fortune-telling. However, if this woman refuses to repent, then the matter is up to the ruler to punish her and warn people of her deeds and of believing her.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family and Companions.
