Hadschi Halef Omar

Hadschi Halef Omar Ben Hadschi Abul Abbas Ibn Hadschi Dawud al Gossarah, literally hajji Halef Omar, son of hajji father-of-Abbas, son of hajji David al Gossarah, is one of Karl May's literary characters. Hajji means "one who has performed the Muslim pilgrimage to Mecca".

Halef is the exceedingly loyal servant, companion and friend of German adventurer Kara Ben Nemsi. Halef accompanies Kara Ben Nemsi through all his adventures in the Middle East from Durch die Wüste to Der Schut. He is a very devout Muslim, and throughout the adventures with Kara Ben Nemsi he tries to convince him of the superiority of Islam.

After many adventures he became Scheik of the Haddedihn of the great tribe of the Schammar. He is married to Hanneh, the "most beautiful wife on earth", and with her has a son called Kara Ben Halef, who in later novels also has some adventures.

The German disco group Dschinghis Khan also released a song entitled "Hadschi Halef Omar" on their 1980 album "Rom." The entire chorus is basically reciting Halef's name.
