The Forty Thieves are the supporting antagonists of the 1996 animated Disney film, Aladdin and the King of Thieves.
The Forty Thieves are a villainous group of bandits led by their chief Cassim (Aladdin's biological father) and his second-in-command Sa'luk where they stole lots of treasure given as gifts for Aladdin and Jasmine during the wedding. Despite their ruthless behavior using weapons to steal, they are not seen inflicting any physical harm against innocent people, as Cassim himself already wrote up a new rule in their code while becoming their leader: never harm the innocent, in which thieves would have to keep to stay in touch with their group.
There were originally 40 thieves hence the name Forty Thieves, however due to the betrayal of Sa'luk, who informed the location to Razoul after being 'replaced' by Aladdin during a fight between them, 32 of the thieves got arrested and somehow seven of them managed to evade them. The 32 thieves vow that Sa'luk will pay for his betrayal, even when Sa'luk closes the door on them. Upon returning to the hideout, Sa'luk then convinced the remaining seven thieves that it was Cassim who was responsible for betraying them and convinced them to mutiny against him.
Eventually, in an act of justice during the climax, Sa'luk ended up being turned to a golden statue by the Hand of Midas as punishment, as well as the seven thieves having turned their boat into solid gold, sinking the boat. It is unknown if the seven thieves survived, or if they got arrested, or if they drowned or not.
