What is "tanukhids"

The Tanûkhids or Tanukh were originally from the Nabataean ( Arabic : نبط) confederation of Arab tribes, sometimes characterized as Saracens. They first rose to prominence in northern Arabia and south of Syria in the 3rd century BC. Both Lakhmid and Tanukhid inscriptions have been found at Umm el-Jimal in Jordan and Nimreh in Syria.The ancient Tanukhi tribal confederation was largely taken over by several branches of the Ishmailite Nabt tribe.
