Horoscope is the prediction of a person’s future based on a comparison of the zodiacal data for the time of birth with the data from the period under consideration. Not only the practice of astrology is haram, but also visiting an astrologer or listening to his predictions, buying books on astrology or reading one’s horoscope are also forbidden.

Since astrology is mainly used to predicting the future, those who practice it are considered fortune-tellers. Consequently, one who seeks his horoscope comes under the ruling contained in the Prophet’s statement:

“The salah (daily prayer) of whoever approaches a fortune-teller and asks him about anything will not be accepted for forty days and nights.” (Muslim)

Allah clearly stated: “And with Him are the keys to the ghayb (all that is hidden), none knows them but He and He knows whatever there is in [or on) the earth and the sea; not a leaf falls, but the knows it. There is not a grain in darkness of the earth nor anything fresh or day, but is written in a clear record.” (Al-An`am 6:59)

The money you may earn through practicing horoscope is forbidden. According to the authentic hadith, The Messenger of Allah (peace be upon him), forbade the sale price of a dog, the earnings of a prostitute and the earnings of a fortune teller.

By the earnings of a prostitute he meant what a woman was given for fornication. The earnings of a fortune teller were what he was given to tell a fortune. (Malik)

Therefore, you have to abandon such a forbidden act and repent to Allah. One of the essential conditions for an accepted repentance is that a person never repeats such a deed again or even has the intention to make it again.
