All khatib or sermon readers in the country have been told to pray for the well-being of the Yang di-Pertuan Agong, the rulers and people in the "doa" after the Friday sermons.

The name of the nation's Muslim leader must be mentioned in Friday sermons in mosques because Islam is the official religion of the country, said former prime minister Tun Dr Mahathir Mohamed.

The government would take stern action against any quarters who threaten harmony in the country by raising sensitive racial and religious issues, said Home Minister Datuk Seri Hishammuddin Hussein.

The Islamic Development Department of Malaysia (Jakim) opines that leaving out the "doa" (prayer) for the Yang di-Pertuan Agong as head of state as well as for the states' rulers is not proper as praying for their well-being is a noble practice.

Penang police have set up a special team to investigate the alleged use of the chief minister's name instead of the Yang di-Pertuan Agong's in the "doa" (prayer) during the Friday sermon at certain mosques in the state.

Home Minister Datuk Seri Hishammuddin Hussein said police had so far received three reports over the "doa khutbah" (prayer during the Friday sermon) issue involving some mosques in Penang.

Datuk Seri Najib Tun Razak wants the police and Penang Islamic Religious Council to conduct a full investigation into the alleged use of Chief Minister Lim Guan Eng's name, replacing the Yang di-Pertuan Agong's, in the "doa" after the Friday sermon at some mosques in the state recently.

PAS Spiritual Leader Datuk Nik Abdul Aziz Nik Mat today declined comment on the issue of the alleged use of Penang Chief Minister Lim Guan Eng's name in the prayer during the Friday sermon in several mosques in Penang.

The Penang government today denied that Chief Minister Lim Guan Eng's name was used instead of the Yang di-Pertuan Agong's in the "doa" (prayer) after the Friday sermon at several mosques in the state.

Using of Penang Chief Minister Lim Guan Eng's name in place of the Yang di-Pertuan Agong's in the 'doa' (prayer) after the Friday sermon must stop immediately as it is in conflict with Islamic ruling.
