KUALA LUMPUR, Nov 16 — There has been no case to prove that adultery occurs during mass sporting events, Youth and Sports Minister Khairy Jamaluddin said, as several opposition MPs raised concerns over the need for Islam-compliant attire for female athletes.

“We take note of the observation, but so far there has not been any case or proof to show that adultery happens at these programmes,” he told Parliament when winding up debate points on Budget 2016.

Earlier when interjecting, PKR's Lumut MP First Admiral (r) Mohd Imran Abdul Hamid cautioned that skimpy attire used by female participants of such events could lead to adultery.

“Because of the interaction where we see sexy clothing that could cause stimulation, we fear that it could lead to adultery. I hope the minister can look into this,” Mohd Imran said.

Responding to more questions from PAS MPs Siti Zailah Mohd Yusoff (Rantau Panjang) and Nik Mohamad Abduh Nik Abdul Aziz (Pasir Mas), Khairy said it is entirely up to Malaysia's athletes if they want to wear clothes that are deemed in line with Islamic principles.

Siti Zailah queried if Putrajaya has a policy on athletes' clothing - especially for female athletes - stressing that Islam-compliant attire is necessary if the federal government is truly pursuing a system of governance that is based on Islamic principles.

“We leave it to the athletes to decide for themselves, so long as they don't contravene the rules of the sport,” Khairy said.

Earlier this month, Malaysians took to Twitter to criticise the attire of cyclists Muhammad Afiq Afify and Mohamad Hafiz Mohamed Sufian after they won gold medals at the Japan Para Cycling Cup 2015.

The duo's purportedly skimpy bicycle shorts sparked a debate on the microblogging site, with some claiming that their skintight yellow-and-black outfits did not sufficiently cover their “aurat,” which refers to parts of a Muslim's body that must be clothed.

Last June, gymnast Farah Ann Abdul Hadi was slammed online for showing her “aurat” and the “shape of her vagina” in the leotard she wore while winning the gold medal at the recent SEA Games.

Both Muslim women and men are prohibited in Islam from exposing their aurat, though criticisms are more often targeted against women.
