As for going to diviners, soothsayers, fortunetellers and their likes who claim to know much about the future and the Ghayb (the Unseen), it is a detestable impermissible practice. Moreover, believing them is worse and even regarded as a sort of disbelief.
He who visits a diviner and asks him about anything, his prayers extending to forty nights will not be accepted.
The Prophet (may peace be upon him) forbade going to fortune tellers and asking them.
If anyone resorts to a diviner and believes in what he says, then he disbelieves in what was revealed to Muhammad (may peace be upon him).
There is no disease that Allah has created, except that He also has created its treatment that may be known to some people and unknown to others.
For every disease there is a medicine, so if the medicine comes upon the disease, it will be cured by the Leave of Allah.
O Allah's servants! Treat yourselves medically, but use nothing unlawful.
May Allah's peace and blessings be upon His servant and Prophet Muhammad, his family and Companions!
