Deputy minister in the Prime Minister's Department, Mohamed Hanipa Maidin has rebuked PAS for claiming that Islam was being undermined by the Pakatan Harapan government.

"I found their arguments to be coloured by emotion and sloganistic tendencies, rather than high intellectualism.

"I am not sure how they measured Harapan's hard work to promote transparency, combat wastage, corruption, and abuse of power through the lens of Islam," Hanipa said in a statement today.

Yesterday, PAS information chief Nasrudin Hasan claimed Muslims were feeling jittery as the top three government posts involving law were held by non-Muslims.

These are attorney-general Tommy Thomas, de facto law minister Liew Vui Keong, and newly minted Chief Justice Richard Malanjum.

Rebutting Nasrudin, Hanipa said Liew had empowered him as his deputy to oversee all legal matters involving Islam and syariah matters.

The Amanah vice-president also said the Federal Constitution draws clear boundaries on the attorney-general's jurisdiction over syariah matters.

As for Malanjum's appointment as chief justice, Hanipa said it was irresponsible to paint the former as anti-Islam based on dissenting judgments in certain cases.

"Such attitude (to paint Malanjum as anti-Islam), belittles the stature and excellence of Islam," the deputy minister said.

While Nasrudin did not cite any specific cases, one incident Malanjum's critics point to is his dissenting judgment in the Lina Joy apostasy case.

However, Lawyer Haniff Khatri Abdulla said it is not fair to say that any judge in the case was anti-Islam or pro-Islam.

Haniff also said that the allegations against Malanjum also maliciously assumed that Islam's constitutional position, as the official religion, allows for discrimination against others based on race or religion.
