The Quran

إِنَّ الَّذينَ آمَنوا وَالَّذينَ هادوا وَالنَّصارىٰ وَالصّابِئينَ مَن آمَنَ بِاللَّهِ وَاليَومِ الآخِرِ وَعَمِلَ صالِحًا فَلَهُم أَجرُهُم عِندَ رَبِّهِم وَلا خَوفٌ عَلَيهِم وَلا هُم يَحزَنونَ

J. M. Rodwell

Verily, they who believe (Muslims), and they who follow the Jewish religion, and the Christians, and the Sabeites¹ - whoever of these believeth in God and the last day, and doeth that which is right, shall have their reward with their Lord: fear shall not come upon them, neither shall they be grieved.

The Sabeites are identical with the Mendaites, or so-called Christians of S. John, residing in the marshy district at the mouth of the Euphrates, but are not the same with the star-worshipping Sabians of Harran in Mesopotamia. See D'Herbelot, Bibl. Or. under the word Sabi; Assemani, Bibl. Or. iii. 2, 609. For curious details as to the elements of the Sabeite religion, see Chwolson's SSabier and SSabaismus I.
