Abudin is a fictional city located in Saudi Arabia. Tintin visits the city after leaving the film camp of his then friend, Roberto Rastapopoulos and a long journey through a desert, avoiding the pursuing Thompson and Thomson. He and Snowy arrive there just as war had been declared after a village Sheik was attacked by two members of an enemy tribe (actually the Thompsons). Tintin was drafted into the army by Corporal Abu-Bin-Dun and he uses a false name, Ali-Bhai.
