It is widely believed that the Rbbl bn Hfʿm grave inscription found at Qaryat al-Fāw is the earliest example of Old Arabic. The ten-line inscription – written in the Sabaic script – attests the common Arabic definite article, ʾl, plus several other non-Sabaic linguistic features. I argue that the definite article is not a suitable diagnostic of genetic affiliation, and other features, such as mimation, the conjunction ʿdky, and more, should also be given consideration. Through a close linguistic examination based on the principle of shared morphological innovations, I demonstrate that none of the morphological innovations which characterize Arabic are attested in this inscription. As such, its language is probably not a descendant of proto-Arabic. Our results further suggest that the ʾl- article, which has previously been used as a marker of Arabic, was simply one of many definite article forms which spread to Arabic, and other Semitic languages of Arabia, through areal diffusion.

Unlike most ancient Arabic poetry, the poems attributed to Umayya b. Abī l-Ṣalt treat subjects that are also prominent in the Quran, such as creation, eschatology, and episodes from Biblical history. The authenticity of this corpus has, however, been the subject of some controversy. After a critical survey of previous scholarship, this article examines one particular passage from the Umayya corpus dealing with the destruction of the ancient tribe of Thamūd, which, it is argued, is likely to be pre-Quranic. The article then proceeds to highlight the crucial differences, both in content and in literary format, that exist between Umayya's retelling of the Thamūd narrative and its earliest Quranic version, and concludes with a number of general remarks on the Quran's religious milieu as reflected in Umayya's literary output.
