Pahang Mufti Abdul Rahman Osman has refused to apologise for an anti-DAP sermon during Hari Raya Aidiladha last week.

Instead, a defiant Abdul Rahman said it is DAP that should apologise for "interfering in Islamic affairs".

He said this in response to Pahang DAP chairperson Tengku Zulpuri Shah Raja Puri who demanded the Pahang Islamic Affairs Department (Jaip) to apologise and retract the sermon.

He said legal action will be taken against Jaip otherwise.

"We will not bow to any quarters that want the department to apologise and retract the AIdiladha sermon text or face legal action.

"It should be they who apologise first for interfering in Islamic affairs like (opposing) the implementation of hudud in Kelantan," Abdul Rahman was quoted as saying in an Utusan Malaysia report today.

He said the sermon was a word of advice to Muslims to be united and not stand with those who challenge Islam.

Abdul Rahman added that he was disappointed with Muslims in DAP who were more keen in defending the party and did not respect the Islamic institutions.

"They (Muslims in DAP) should be defending Islamic clerics and institutions but they want to sue us and demand that we apologise," he said.

The sermon had said Muslim joining DAP were going against Islam and was read out by Abdul Rahman at the Sultan Ahmad Shah 1 state mosque.

Muslims in DAP include national laureate A Samad Said, law professor Abdul Aziz Bari and historian Ariffin Omar.
