Father Kabsha's Son is also referred to in Islamic sources as having been a member of the Quraysh (Association) because of Tachkastan's relationship to the "ignorant Arab" (identified by A.J. Deus as Ilyas/Iyas ibn Qabisa) that Khosrow II appointed to rule Lakhmidia was in the Association of Persian Nobles.
Islamic sources indicate that this Association was based in controlled Makah (originally spelled with one k).
The earliest available description of the location of Makah identifies it with the area of Al-Anbar in the Mesopotamian desert between [https://en.wikipedia.org/wiki/Al-Khalidiya,_Iraq Al-Kaldiya] and Carra.
