The Ja'alin, Ja'aliya, Ja'aliyin or Ja'al (Arabic: جعليون) are an Arab or Arabised Nubian tribe in Sudan. The Ja'alin constitute a large portion of the Sudanese Arabs and are one of the three prominent Sudanese Arab tribes in northern Sudan - the others being the Shaigiya and Danagla. They trace their origin to Ibrahim Ja'al, an Abbasid noble, whose clan originally hailed from the Hejaz in the Arabian Peninsula and married into the local Nubian population. Ja'al was a descendant of al-Abbas, an uncle of Muhammad. The Ja'alin formerly occupied the country on both banks of the Nile from Khartoum to Abu Hamad. According to a source, the tribe allegedly once spoke a now extinct dialect of Nubian as late as the nineteenth century. Many Sudanese politicians have come from the Ja'alin tribal coal
