Located in the southwestern part of Penang island, Kampung Seronok is the birthplace of a deviant Islamic cult known as Taslim (also known as Agama Matahari).
The cult was introduced by Syed Muhammad Syafre bin Syed Sailuddin (also known as Haji Ahmad Matahari), who claimed to be a descendent of the Prophet Muhammad s.a.w. After arriving in Malaya from Madura, he founded a settlement in Bayan Lepas in 1872, which he named Kampung Haji Muhammad. In 1946, the kampung was renamed Kampung Seronok as suggested by a British engineer named D.W. Grehan. It was said that Grehan was impressed with the festivities of the village during his visit. 
The cult in Kampung Seronok was rather bizarre and at odds with the teachings of Islam. Rumours said that all Taslim members met once a year at the cult’s main headquarters at Kampung Seronok.

Once the clock struck 12, they would then engage in sexual activities with anyone in the dark. 
Amongst the teachings of the cult leader are : - Followers surrender their children, wives, and properties to the [cult leader] or his successor in Kampung Seronok, Bayan Lepas, Penang; - There is no need for prayers (solat) - The Islam of a person is only valid when he meets the [cult leader] at Kampung Seronok; - Friday is assumed to be the day when Prophet Adam and Eve met, so intercourse were encouraged during Zohor on Fridays. - Hajj is performed by climbing Bukit Payong in Bayan Lepas, Penang; - Allow to marry each other "spiritually" (nikah batin) - Reject the existence of heaven, hell, and doomsday; - Permits adultery through the concept of "nikah batin";
Syed Muhammad Syafie died in 1913. His sons and descendants took over the role of the cult leader. During the 1940s to 50s, the Taslim cult grew in size and popularity. After many decades, a fatwa was issued by the mufti of Penang's office in 2010, declaring that the Teachings of Taslim or the Teachings of Haji Ahmad / Muhammad Matahari deviate from the true teachings of Islam. Therefore, Muslims are forbidden to practice such teachings, and Muslims who practice them can be subject to legal action.

Research into the sect is hard to be conducted as former followers of the deviant sect adopt the "let bygones be bygones" (yang lepas tu lepaslah) mindset. 
Officially, it is no longer practised, although some believe traces of the sect can still be traced as shown in this picture of a house in Kampung Seronok with a symbol of the sun on its roof.
However, it should be noted that motifs such as sun, star, flowers and other natural elements are common in traditional Malay architecture.
