No one can question the hudud law because it is Allah's law and its implementation is compulsory in Islam, Mufti of Perak Tan Sri Dr Harussani Zakaria said.

However, he said Muslims can give constructive criticisms to improve the implementation of the law.

"I don't know what (aspects) were being questioned, is it the methods (of implementation) or is it not perfect?...I don't know, but as far as hudud is concerned, anyone who fight against Allah's law shall receive punishment from Allah.

"I'm confident that what was tabled was hudud law, but I had not looked into the methods of implementation...maybe it's the methods that were being criticised...hudud law must be implemented, it is compulsory," he said after launching the Baitul Ridzuan Tarbiah Complex project in Kampung Manjoi here

The Mufti said this in response to the move taken by some quarters in questioning the proposed implementation of hudud in Kelantan.

Harussani said Muslims should stay united and accept the law rather than fighting each other over it.

"They probably had been thinking too much about it, but when their opinion was rejected by others, they try to defend it.

"Generally, in Islam, no one can question hudud law. Questioning hudud is like questioning Allah's law," he said.
