Thank you for the links agentx but sadly that site is largely Bogus and is designed to promote the idea that Mandaeans are Sabians so that the Mandaeans can claim sanction of the Shariah state.

Basically the early Arab writers closest to the time of Mohammed who wrote about the Sabians in what could be classified as ancient literature stated their views as follow
Sabiah Hunafa ia (the way of a Haneef) a somewhat disorganised religion (10) following the Din of Noah (1) as a sect who read the Zabur (1,3) akin to Christianity (2). They appear to be between Judaism and Magianism (4) but are in fact closer to Judaism (5). Sabis recognise the practice of The Prophet (SAW) in going to the caves prior to his inspiration, as in accordance with the Sabi quest for Tawheed (6). Because of many similarities with the Sabians, The Prophet (SAW) and his companions were often considered to have been Sabians (7). Most specifically this was because of the Sabians shahada ?La ilaha il Allah? (. Other characteristics of the Sabi religion follow (9). They have five daily prayers (though Zohar joins Asr while Maghrib joins Isha). They know Allah (SWT) as the Lord of lords and GOD of gods. They speak to angels in their meditations which has led to the erroneous beliefs among some that Sabis worship angels. They use the sun for a Qiblah. They fast for 30 days. They believe in all prophets reiterating the religion of Noah and not in the same way as the muslims believe in The Seal of The Prophets.
The root-meaning of the word Sabi means Proselyte, and is identical in usage with the Greek words Sebomenoi or Theosebes and to a lesser extent Phobeomenoi(11).
After the time of the Caliph al-Mamun, Arab writers seem to virtually cease writing about Sabiah Hunafa ia and only wrote about Sabi`ah Mushrikeen.

Rabi?ah ?ibn ?Ubbad (who lived at the same time as Mohammed) wrote
"I saw the prophet when I was a pagan. He was saying to the people, ?if you want to save yourselves, accept that there is no God but Allah? At this moment I noticed a man behind him saying ?he is a sabi.? When I asked somebody who he was he told me he was ?Abu Lahab, his uncle." *
Both ?Ibn Jurayi (d. 767) and ?Ata ?ibn Abi Rabah (d.732) wrote
"I saw the prophet when I was a pagan. He was saying to the people, ?if you want to save yourselves, accept that there is no God but Allah? At this moment I noticed a man behind him saying ?he is a sabi.? When I asked somebody who he was he told me he was ?Abu Lahab, his uncle' Of the relationship between the Sabians who lived in Sawad (in Iraq ) and Mohammed it is mention that the polytheists of Mecca were heard to say of Mohammed "he has become a Sabian." *
