The Islamic Ruling on Horoscopes

Not only the practice of astrology is Haram (forbidden) but also visiting an astrologer and listening to his predictions, believing in predictions, buying books on astrology or reading one’s horoscope are also forbidden in Islam. Since astrology is mainly used to predicting the future, those who practice it are considered fortunetellers. Consequently, one who seeks his horoscope comes under the ruling contained in the Prophet’s (S.A.W.) Hadith:

"He who goes to one who claims to tell about matters of the Unseen and believes in him, his Salat (prayers) will not be accepted for forty days." (Muslim: 2230)

The punishment in this hadith is simply for approaching the asking the astrologer, even if one is in doubt about the truth of his statements. If one is in doubt about the truth or falsehood of astrological information, he is in doubt about whether or not others know the unseen and the future besides Allah. This is a form of Shirk (the deification or worship of anyone or anything besides Allah) because Allah Has clearly stated:

“And with Him are the keys of the unseen; none knows them except Him. And He knows what is on the land and in the sea. Not a leaf falls but that He knows it. And no grain is there within the darknesses of the earth and no moist or dry [thing] but that it is [written] in a clear record." (Surah Al-Anaam 6:59) 

Say, "None in the heavens and earth knows the unseen except Allah, and they do not perceive when they will be resurrected." (Surah Al-Namal 27:65)

If, however, one believes in the predictions of their horoscope, whether spoken by an astrologer or written in books of astrology, he falls directly into Kufr (disbelief) as stated by the Prophet (S.A.W.) in the following Hadith:

"Whoever approaches an oracle or fortune-teller and believes in what he says, has disbelieved in what was revealed to Muhammad.” [Tirmidhi:135 and reported by Abu Hurairah (R.A.)]

Like the previous Hadith, the Hadith literally refers to the fortuneteller but it is just as applicable to the astrologer. Both claim knowledge of the future. The astrologer’s claim is just as opposed to the Tawheed (Oneness of Allah) as the ordinary fortuneteller. He claims that people’s personalities are determined by the starts, and their future actions and the events of their lives are written in the starts. The ordinary fortuneteller claims that the formation of tea leaves at the bottom of a cup, or lines in a palm tell him the same thing. In both cases individuals claim the ability to read in the physical formation of created objects knowledge of the unseen.

Belief in astrology and the casting of horoscopes are in clear opposition to the letter and spirit of Islam. It is really the empty soul, which has not tasted real Imaan (belief) that seeks out these paths. Essentially these paths, represents a vain attempt to escape Qadr (fate). The ignorant believe that if they know what is in store for them tomorrow, they can prepare from today. In that way, they may avoid the bad and ensure the good. Yet, Messenger of Allah (S.A.W.) was told by Allah to say:

“Say (O Muhammad SAW): "I possess no power of benefit or hurt to myself except as Allah wills. If I had the knowledge of the Ghaib (unseen), I should have secured for myself an abundance of wealth, and no evil should have touched me. I am but a warner, and a bringer of glad tidings unto people who believe.” (Surah Al-Araaf 7:188)

True Muslims are therefore obliged to stay far away from these areas. Thus, rings, chains, etc., which have the signs of the zodiac on them should not be worn, even if one does not believe in them. They are part and parcel of a fabricated system which propagates kufr and should be done away with entirely. No believing Muslim should attempt to guess his sign. Nor should he or she read horoscope columns in newspaper or listen to them read. And, any Muslim who allows astrological predictions to determine his actions, should seek Allah’s forgiveness and renew his Islam.
