While living in Shamar, Sadiq wanted to become a tour guide when he grew up, and spent therefore most of his time practicing to be a tour guide. During this period, Sadiq found a role model in Musaid, a local tour guide. Over time, Sadiq came to idolize Musaid and view him as the best tour guide in Shamar due to how Musaid was a fast talker, did not take no for an answer and would not give up until a potential customer said yes, which only drove Sadiq to pursue his dream with more effort, and as well try to memorize his personal slogan, though with limited success.
During the events of Sonic Unleashed, Sadiq met Sonic the Hedgehog and Chip when they first arrived in Shamar. There, Sadiq offered them to go to the souvenir shop or the tourist hot spot, before attempting to say his slogan, but could not get it right. As Sonic and Chip tried to leave, Sadiq remarked that Musaid made it look easy and claimed disheartened that he would never get good at this.
Later on, Sadiq met Sonic and Chip again and tried to offer them a tour again, but still failed to get his slogan right. When Sonic asked what he was doing, Sadiq explained to him about his dream and why he idolized Musaid so much. Sadiq then heard from Sonic and Chip that they were looking for someone to take over Musaid's business, as Musaid was (unwillingly) going to Mazuri before being asked if he wanted that position. Instantly, Sadiq accepted the offer, though he knew he had to keep practicing, and told Sonic to call him "Musaid II" as he promised to become the second greatest tour guide who ever lived. Later on, Sadiq met Sonic and Chip, where he proclaimed that he would become the number-one tour guide in Shamar before asking Sonic and Chip to say thank you to Musaid and that he wished him the best of luck.
Sadiq never made an in-game appearance during the Wii/PlayStation 2 version of Sonic Unleashed. He did however appear during a pre-rendered cutscene, where he and the rest of Shamar's residents rejoiced as the world returned to normal, following Perfect Dark Gaia's defeat at the hands of Super Sonic and the Gaia Colossus.
Sadiq dreams of becoming the number-one top tour guide in Shamar when he grows up. An admirable lad, Sadiq knows there is no cutting corners if you want to fulfill your dreams and practices therefore his skills as a tour guide very hard. He looks very much up to Musaid as his role model and admires Musaid's skills as a tour guide.
