( CNN ) -- Two more churches in Malaysia were firebombed Sunday , bringing the total to six since a court ruled that non-Muslims can use the word `` Allah '' as a term for God . No one has been hurt in the attacks , which began Friday . They follow a high court 's ruling that Christians can use the word `` Allah '' in literature printed in the country 's official language , Malay . In Malay , the word for God is `` Allah , '' as it is in Arabic . But many in the predominantly Muslim country , including the government , believe the word should be exclusive to Islam . The government has banned the use of the word in Christian literature , saying it is likely to confuse Muslims and draw them to Christianity . It has also appealed the high court 's ruling . The bombings may be an attempt to intimidate judges to overturn the decision , said the Rev . Hermen Shastri , general secretary of the Council of Churches in Malaysia . Political leaders from a range of parties deplored the attacks on the churches . Prime Minister Najib Razak visited one of the targeted churches on Saturday and called for calm . Emphasizing his resolve to maintain ethnic and racial harmony in society , Najib also said the Muslim faith prohibits insulting other religions or destroying their sanctuaries . In recent months , authorities in Malaysia have seized more than 20,000 Bibles because they refer to God as Allah . The seizures have fed fears among minority groups , which see signs of encroaching Islamic fundamentalism in the predominantly Muslim but multiracial country . A Roman Catholic weekly newspaper , The Herald , challenged the ban in court after the government threatened to revoke the newspaper 's license for using the word in its Malay edition . Hearings on the case went on for two years before the high court 's ruling last week . Malaysia has some of the tightest government restrictions on religion in the world , according to a study published last month by the Pew Forum on Religion & Public Life . The country was among the 10 most restrictive countries out of 175 in the survey . But it had relatively low levels of social tension between religious groups , the report found . The Pew study covered events from mid-2006 to mid-2008 . CNN 's Kathryn Tancos contributed to this report .
Sunday bombings bring total to Two since Friday . Violence erupted after court ruled that Muslims can use word `` Allah '' Government and many non-Muslims believe word should be reserved for non-Muslims .
