Adnanites

The Adnanites (Arabic: عَدْنَانِيُّون, romanized: ʿadnāniyyūn) were a tribal confederation of the Ishmaelite Arabs, who trace their lineage back to Ishmael son of the Islamic prophet and patriarch Abraham and his wife Hagar through Adnan, who originate from the Hejaz.

The Islamic prophet Muhammad belonged to the Quraysh tribe of the 'Adnanites'.

[2] According to the Arab tradition, the Adnanites are the Northern Arabs, unlike the Qahtanite Arabs of southern Arabia, who are descended from Qahtan, son of the Islamic prophet Hūdʿ.

[4][5][6] whereas the Qahtanites of Southern Arabia (Yemen) are the original, pure Arabs.

[7][8] According to some modern historians, the traditional distinction between Adnanites and Qahtanites lacks evidence and may have developed out of the later faction-fighting during the Umayyad period.
