The Khagga are tribe of Qureshi origin and are said to belong to the Quraish community. They are mostly found in south-west Punjab, Pakistan and mainly speak Seraiki.
Khaggas claim their ancestry from Hazrat Jaffer Tayyar and are descendants of Shah Jalal-ud-Din, who was the disciple of Hazrat Awais Kerni, a saint of Awaisi chain of Sufis. He is believed to have arrived in Multan during the times of Hazrat Sadar-ud-din (son of the Sufi Hazrat Baha-ud-Din Zakariya) and died in the year 700AH/1300AD.
