Numerology is a branch of Astrology and fortune telling. Both are Haram and in conjunction to this so is numerology. Numerology is the study of the occult meanings of numbers and their so called influences on human life and creation.
To practice something such as this is haram, and it is also haram to go to them for help. A persons iman is at great risk.

The word ?Arraafun? in the Hadith incorporates soothsayer, fortune tellers, clairvoyance, oracle etc.
One should seek the cures to ones problems in Allah through the Quran and the way shown to us by Rasulullah Salallahu Alaihi Wassalam.
