Islamic astrology (also Arabic astrology, Persian-Arabic astrology), in Arabic ilm al-nujum or ilm al-falak is the study of the heavens by early Muslims. In early Arabic sources, ilm al-nujum was used to refer to both astronomy and astrology. In medieval sources, however, a clear distinction was made between ilm al-nujum (science of the stars) or ilm al-falak (science of the celestial orbs), referring to astrology, and ilm al-haya (science of the figure of the heavens), referring to astronomy. Both fields were rooted in Greek, Persian, and Indian traditions. Despite consistent critiques of astrology by scientists and religious scholars, astrological prognostications required a fair amount of exact scientific knowledge and thus gave partial incentive for the study and development of astronomy.

Opinions of Contemporary Scholars

According to jurists, the study of astronomy (ilm al-haya) is lawful, as it is useful in predicting the beginning of months and seasons, determining the direction of salat (prayer), and navigation. They agree that this branch of science be used in determining the beginning and end of the month of Ramadan. As for astrology, this is considered by most Islamic scholars as haram (unlawful), as knowledge of the Unseen is known only by Allah. Dr. Husam al-Din Ibn Musa `Afana, a Professor of the Principles of Fiqh at Al-Quds University, Palestine, states the following:

"First of all, it is worth noting that the Arabs knew astronomy a long time ago. They would predict time through observing the movements of stars. According to the scholars of Shar`iah, there are two terms confused in many people's minds when it comes to dealing with the question in hand. These terms are astronomy and astrology. Astronomy is the science that deals with studying the movements of the celestial bodies and reducing observations to mathematical order. That science is useful in determining time, seasons, the direction of Prayer, etc. Astrology, on the other hand, is concerned with studying the positions and aspects of celestial bodies in the belief that they have an influence on the course of natural earthly occurrences and human affairs. Astrologists believe that the movements of stars have an influence on people's lives. Both Muslim astronomers and ^* scholars refuse the prophecies of astrologists."excerpted from a lecture given by Dr. Yusuf Marwah under the title Astronomy and the Beginning of the Lunar Months

On the other hand, scholars agree that astrology is a prohibited field of study. Imam Ibn Taymiyah said: “Astrology that is concerned with studying the positions and aspects of celestial bodies in the belief that they have an influence on the course of natural earthly occurrences and human affairs is prohibited by the Quran, the Sunnah, and the unanimous agreement of the Muslim scholars. Furthermore, astrology was considered forbidden by all Messengers of Almighty Allah.”

The Saudi scholar, Muhammad ibn al Uthaymeen, said: “Astrology is a kind of sorcery and fortune-telling. It is forbidden because it is based on illusions, not on concrete facts. There is no relation between the movements of celestial bodies and what takes place on the Earth.”Islamonline.com

Quranic Verses & Ahadith Relating to Astrology

---

Before the advent of Islam, people believed that the sun and moon might eclipse when a great figure died. During the Muhammad's lifetime, it happened that the sun eclipsed on the same day when Muhammad’s son Ibrahim died. The people then thought that it had eclipsed because of the Prophet’s son’s death. On knowing this, Muhammad led them in the Eclipse Prayer and then delivered a speech saying: “The sun and moon are but signs of Allah; they do not eclipse because so-and-so died or was born.”

This hadith indicates that Muhammad denied all relation between the movements of the heavenly bodies and events on the Earth. Ibn `Abbas reported that Muhammad said: “He who has acquired some knowledge of astrology has acquired some knowledge of sorcery; the more he acquires of the former the more he acquires of the latter.”Reported by Ahmad, Abu Dawud, and Ibn Majah

Commenting on this hadith, the Yemeni scholar Muhammad ash-Shawkani (d.1834), said that the Prophet compared between astrology and sorcery because sorcery was known to be forbidden; and so, he who would get some knowledge of astrology would do something forbidden and would be sinful.Nayl Al-Awtar, vol.7, p.207

It was also reported by Ibn Abbas that the Prophet Muhammad said: “He who uses astronomy for something other than what Almighty Allah has made lawful would be practicing sorcery. Astrologers predict knowledge of the future, and he who does so is a sorcerer, and sorcerers are disbelievers.”See Meshkat Al-Masabeeh, vol. 2, p. 1296

Also, Ibn Mihjan reported that the Prophet said: “I fear on account of my nation three things after my death: (I fear that) their Imams (leaders) would oppress them, (that) they would believe in astrology, and (that) they would disbelieve predestination.”Reported by Ibn `Asakir and Ibn `Abdul-Barr

Abu Hurayrah also reported that the Prophet said: “He who goes to a fortune-teller to ask him about something, his Prayer will not be accepted for forty days.”Reported by Muslim

Abu Hurayrah also reported that the Prophet said: “He who goes to a soothsayer or a fortuneteller and believes what he says exhibits disbelief in what has been sent down to Prophet Muhammad (from Allah).”Al-Albani said in Sahih At-Targhib wa At-Tarhib, vol. 3, p. 172, that this is an authentic hadith

Contemplating the last two ahadith reported by Abu Hurayrah, it is to be noted that mere going to fortune-tellers is a sin that incurs upon a Muslim who commits it that his prayer is not accepted for forty days, and that believing what fortunetellers say renders a Muslim a disbeliever in what has been sent down to Prophet Muhammad. This is because Allah says in the Quran: “Say (O Muhammad): None in the heavens and the earth knoweth the Unseen save Allah; and they know not when they will be raised (again).”Quran, An-Naml: 65

Allah also says: “(He is) the knower of the Unseen, and He revealeth unto none His secret, save unto every messenger whom he hath chosen, and then He maketh a guard to go before him and a guard behind him That He may know that they have indeed conveyed the messages of their Lord. He surroundeth all their doings, and He keepeth count of all things.”Quran, Al-Jinn: 26-28
