Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whoever goes to a soothsayer and believes what he says has disbelieved in what was revealed to Sayyiduna Muhammad (peace and blessings be upon him)."
Al-Bazzar recorded it, and its narrators are the narrators of the Sahih, except Uqbah bin Sinan, who is thiqah (trustworthy).
