Banu Kalb
In 700/01, al-Walid patronized the construction or expansion of Qasr Burqu', a fortified Syrian Desert outpost connecting Palmyra in the north with the Azraq oasis and Wadi Sirhan basin in the south, ultimately leading to the Muslim holy cities of Mecca and Medina. His patronage is attested by an inscription describing him as "the emir al-Walid, son of the commander of the faithful". According to the historian Jere L. Bacharach, al-Walid built the nearby site of Jabal Says, likely as a Bedouin summer encampment between his base of operations in al-Qaryatayn and Qasr Burqu'. Bacharach speculates that al-Walid used the sites, located in the territory of Arab tribes, such as the Banu Kalb, to reaffirm their loyalty, which had been critical to the Umayyads during the civil war.
