The Quda'a (Arabic: قضاعة, romanized: Quḍāʿa) were a confederation of Arab tribes, including the powerful Kalb and Tanukh, mainly concentrated throughout Syria and northwestern Arabia, from at least the 4th century CE, during Byzantine rule, through the 12th century, during the early Islamic era. Under the first caliphs of the Syria-based Umayyad Caliphate (661–750), the Quda'a occupied a privileged position in the administration and military. During the Second Muslim Civil War (683–692) they allied with South Arabian and other tribes in Syria as the Yaman faction in opposition to their rivals, the Qays confederation, in what became a rivalry for power and influence which continued well after the Umayyad era. In forging this alliance, the Quda'a's leaders genealogically realigned their descent to the South Arabian Himyar, discarding their north Arabian ancestor, Ma'add, a move which elicited centuries-long debate and controversy among early Islamic scholars.
