Is the ruling on one who goes to a soothsayer—even if he does not claim to know the unseen—the same as one who disbelieved in Allah, denied His verses, and did not submit?

A Muslim who goes to a soothsayer and believes him, thinking that the soothsayer knows the unseen, commits an act of disbelief that expels him from the fold of Islam, because knowledge of the unseen belongs to Allah alone. However, regarding one who believes him while holding the conviction that the soothsayer does not know the unseen but rather obtains his information from Jinn, some scholars have said that this constitutes an act of disbelief that expels one from the fold of Islam, while others have said it is disbelief short of outright disbelief (i.e., a major sin). This latter opinion is the more probable one. Repentance nullifies what came before it, even if it was major disbelief, and evil deeds are transformed into good deeds if a person repents, believes, and performs righteous actions.
