At the beginning of the grand finale show, Marion Caunter and Awal Ashaari informed Faizal that he was eliminated, but he was given another chance to perform for the grand prize. His first original single, Mahakarya Cinta, a song composed by Audi Mok, made its debut in the Grand Finale of One in a Million. He finished as runner-up to Suki Low. Faizal released a single, Kasih Tercipta, as part of the soundtrack for the local film Waris Jari Hantu. He was also named as the sole Malaysian spokesperson for DC Superheroes clothing, as he was famously noted for wearing T-shirts with the Superman logo throughout One in a Million. He also recorded Gemuruh, the theme song for My Starz LG.
On 13 January 2008 Faizal created controversy by removing his shirt to bare his chest and also his belt "live" on television during 8TV's fourth anniversary concert. 8TV's management took action by giving him strict warnings and requiring him to be involved in charity work for six months. In addition, two days after the incident 8TV held a press conference where Faizal apologized to all who were offended by the stunt. As a result, on 19 January, the Malaysian Communications and Multimedia Commission (MCMC) stated that it would ban him from appearing on television for three months, and also bar 8TV from airing live or tape-delayed entertainment programmes throughout the same period, effective 15 January. Days after the end of the ban, the Mufti of Perlis, Dato' Dr. Asri Zainul Abidin, issued a grievance[clarification needed] to TV3 against having Faizal perform at the Konsert Jom Heboh, which was held in the first weekend of May.
