Discussions on the constitutionality of implementing hudud is permitted but not questioning the nature of the law itself, said inspector-general of police Khalid Abu Bakar.

"Do not comment on matters pertaining to Islamic laws. If you want to discuss hudud in terms of its constitutionality, then that would not be a problem," he told a press conference today.

"Don't comment on the law itself, saying hudud is unfair, that means you are questioning it," he added.

Khalid ( right in photo ) said this condition was not only restricted to comments regarding Islam but all religions.

"No one should make any comments against any religion because we would take action," he warned.

When asked on the police’s role should the Kelantan government is successful in implementing hudud, Khalid said the state government must undergo many steps before the Islamic criminal law can be implemented.

“They have to first amend the constitution. If there are discrepancies between the laws (civil and Islamic), it (hudud) cannot come into effect,” he said, declining to comment further as he was “not the right person” to talk on matters pertaining to hudud.

Khalid yesterday had warned Malaysians not to question Islam and hudud as it may provoke retaliation from the radical Islamist group, the Islamic State (IS).

“I would like to remind (the public) who make comments on Islam and hudud not to simply comment, (because) you are inviting retaliation from IS supporters,” he told reporters yesterday.

Khalid said the country was facing a threat from the extremist group, and intelligence reports reveal that they were planning an attack in the country.
