One of the titles that the Ghassanid sovereigns were known for was “Malik Al-Dimashq” or “Saheb Al-Dimashq” which translates to “King of Damascus” or “Owner of Damascus”. The title Sahib or Saheb (/ˈsɑːhɪb/; Arabic: صاحب) is an Arabic title originally meaning ‘companion’. It was historically used for the first caliph Abu Bakr in the Quran. The title is still applied to the caliph by Sunni Muslims.
That’s how Prophet Mohamad, founder of Islam, addresses the Ghassanid King Al-Harith Ibn Abu Chemor (or in some transliterations “Abi Shamir”) in his famous letter inviting the monarch to join the Muslim religion (6 AH or 628 CE)
It’s a public and notorious fact that the current division of the Middle East is an artificial creation by British and French bureaucrats, the infamous “1916’s Sykes–Picot Secret Agreement”, a treaty between the United Kingdom and France, with assent from the Russian Empire and the Kingdom of Italy, to define their mutually agreed spheres of influence and control in an eventual partition of the Ottoman Empire with the end of WWI.
The illegal attempt of installing a Hejazi monarch in Syria from the Hashemites was also a British artificial move that failed miserably. The so-called “Arab Kingdom of Syria” (Arabic: المملكة العربية السورية, al-Mamlakah al-‘Arabīyah as-Sūrīyah) was a self-proclaimed, unrecognized state that began as a “fully and absolutely independent… Arab constitutional government” announced on 5 October 1918 with the permission of the British military, gained de facto independence as an “Emirate” after the withdrawal of the British forces from OETA East on 26 November 1919, and was proclaimed as a Kingdom on 8 March 1920.
As a “Kingdom,” it existed only a little over four months, from 8 March to 25 July 1920. During its brief existence, the kingdom was led by Sharif Hussein bin Ali’s son Faisal bin Hussein. Despite its claims to the territory of Greater Syria, Faisal’s government controlled a limited area and was dependent on Britain which, along with France, generally opposed the idea of a Greater Syria and refused to recognize the kingdom. The kingdom surrendered to French forces on 25 July 1920.
The Ghassanid kings, princes, and sheiks never stop claiming their rights over the Levant (in Arabic Ash-Sham) and the bloodline remains unbroken and the international legal claim absolutely germane.
