A Sabaean is an individual who is a member of an ancient people, the Sabaeans, who lived in what is classed as modern-day Yemen.

The French version of "Sabaean", descendant of the Queen of Sheba (Saba in Arabic, matriarch of the Ethiopian royal bloodline). In Spanish, it is a version of Xavier, which means "bright" as a star. The Bible refers to Sabaeans as a tribe of star worshippers respected by all.

The ancient Yemeni alphabet (also known as musnadالمُسند) branched from the Proto-Sinaitic alphabet in about the 9th century BC. It was used for writing the Yemeni Old South Arabiclanguages of the Sabaean, Qatabanian, Hadramautic, Minaean, Himyarite, and proto-Ge'ez (or proto-Ethiosemitic) in Dʿmt.

Even in Ur, the one true God called Abraham to come out and leave the idolatry of Ur. Thus, it seems from an early part of his life, Abraham had an awareness of the one true God, or at the vert least was somewhat separated from a total commitment to the moon God, such that almighty God was able to call him out and he was willing to go.

Throughout scripture Abraham is known as a man of faith, referring to his dedication to the one true God of the Bible and not just faith for its own sake or faith in general. If Abraham had been a follower of the Sabean religion, then there would have to have been a time when he forsook this and separated himself to seek the one true God. It is certainly possible that this happenned, but this would be only conjecture with no documented support, but there is plenty of documented support for him being a faithful believer in the God of the Bible from start to end.
