The Levant and the orientalist theory
Countering Al-Kalbi's established theory, European orientalists started to formulate a theory in the late 19th century that the Arabic Hejazi script emerged in the early 6th century in the Levant. This theory was based on three dated inscriptions that were discovered in parts of Syria.
The first was an Arabic-Greek inscription discovered by the famous French explorer William Henry Waddington (1826-1894) in the southern Syrian village of Harran al-Lajah. The inscription belongs to an Arab dignitary named Sharahil ibn Thalem who erected a shrine to honour a Christian saint and immortalise his victory over the Jews of Khaybar, a historical town in Saudi Arabia's western region.
The inscription reads:
"I am Sharahil ibn Thalem, and I have erected this martyrdom shrine in the year 463 (in the Bosra Calendar, corresponding to 568 AD) a year following the ruining of Khaybar."
In the parallel Greek text, Sharabil also mentions the Christian saint, John the Baptist.
Relatedly, the renowned Arab mediaeval historian Al-Tabari mentions that a king of the pre-Islamic Arab Ghassanids who lived in the southern Levant named Al-Harith ibn Thalem attacked and destroyed Khaybar upon the command of Al-Harith ibn Jabalah Al-Ghassani.
This means it is possible that Al-Harith ibn Thalem is no other than Sharahil ibn Thalem, who made the inscription of Harran, but Arab historians confused his name with the name of Al-Harith Al-Ghassani, thus the name Al-Harith ibn Thalem, which is commonly used in the tales of pre-Islamic Arabs.
Subsequently, other similar inscriptions were discovered across the Levant.
The oldest mentions a number of Arab Christian figures like Al-Sharh ibn Manaf, Hani' ibn Imru' al-Qais, and Al-Sharh ibn Saad amongst others, who built a church in the area of Khirbet Zabad, south of Aleppo, in the year 511 AD, and inscribed that date in Greek, Syriac, and Arabic. Since the 1930s, the prevalent belief was that this is the oldest inscription in the Arabic Hejazi script.
In the 1970s, another inscription was found in Mount Sais to the east of As Suwayda in Syria, mentioning Ibrahim ibn Mughirah al-Awsi, who was dispatched on a military exploration mission in the desert by Ghassanid King Al-Harith ibn Jabalah. The inscription dates back to 529 AD.
Several other inscriptions in the Hejazi script were later discovered, but none of them was dated, which makes them of little historical value in the quest for the origin of the Arabic script. One of these is the second Umm Al-Jimal inscription discovered in the northeast of the Jordanian desert.
