إِنَّ الَّذِينَ آمَنُوا وَالَّذِينَ هَادُوا وَالصَّابِئُونَ وَالنَّصَارَىٰ مَنْ آمَنَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ وَعَمِلَ صَالِحًا فَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ
Indeed, those who believed and those who were Jews or Christians or Sabeans [before Prophet Muḥammad (ﷺ)] – those [among them] who believed in Allah and the Last Day and did righteousness – will have their reward with their Lord, and no fear will there be concerning them, nor will they grieve. (Qur’an: 2:62)

If you are like me, you might have glossed over the mention of the Sabians the first few hundred times you read this verse and those like it. Mysteriously sandwiched between two groups of people we feel we know about, the Jews and the Christians, we know less about the Sabians in our times. Not only that, but many Muslim scholars appear to have been perplexed as to their true identity and disagreed about who they are, what they believe, and their status vis-a-vis the Muslim community. Many contemporary scholars have tried, but few have arrived at a viable conclusion. It, thus, remains a mystery… perhaps, a mystery school.
My hunch is that the Mysteries of the Greeks – and later the Freemasons and other New Age groups – are what classical Islamic sources refer to as Ṣābi’ah (Sabianism), a complex and multifarious religious tradition that merged different fields of knowledge into its spiritual worldview. Like the Ancient Mysteries described in esoteric sources of modern times, it was thought to be the primordial religion of mankind going back to Adam. It is most often associated with Hermes (Tehuti/Thoth in Egypt, Enoch, in the Bible and Idrīs in the Qur’an). Over time it suffered from corruption and experienced internal reform and slowly dissipated from public attention. Sabianism was overshadowed by other religious movements in the Near East, occasionally taking on different names and descriptions depending on the language, reformer, or public sentiments of the time.

Christopher Buck, in his article, The Identity of the Sabi’un: An Historical Quest, examines the evidences for the various accounts of early Muslim encounters with so-called Sabians according to the listing of Jacques Waardenburg:
- Mazdaeans of Mesopotamia, Iran and Transoxania
- Christians of various denominations
- Nestorians of Mesopotamia and Iran
- Monophysites of greater Syria, Egypt, and Armenia
- Orthodox Melkites of greater Syria
- Orthodox Latins of North Africa
- Arians of Spain
- Jews of Mesopotamia and Iran, greater Syria, and Egypt
- Samaritans of Palestine
- Mandaeans of south Mesopotamia
- Harranians of north Mesopotamia
- Manichaeans of Mesopotamia and Egypt
- Buddhists and Hindus of the Sind
- Indigenous religions of east Africa (172-173)
Were the early Muslims so oblivious that they went all over the world calling every unfamiliar religious denomination Sabians or did their understanding differ from ours? In future posts, I will attempt to unravel this mystery, step-by-step until we see that classical Muslim writers referred to the Ancient Mystery Schools as Sabianism.
