Abstract: In the development of Muslim community, mosque is considered as a nerve centre. Though varying in dimensions and structures, the mosque becomes a place of worship 5 times a day, as well as a symbol for the diffusion of truly Islamic knowledge. Since, the approach of Islamic values was introduced by the Malaysian government in 2004, the mosques throughout the country have actively promoted the new ways of improving the life of Muslims, especially among Muallaf. This study is an attempt to examine the administration and activities of the mosques in supporting the ideas of Islamic values. Friday’s khutbah (sermons), religious preachings, forums as well as the celebration of various events in the Islamic calendar will be analysed in order to illustrate how the new understanding of Islam is being promoted to the Muallaf. This study argues that the mosque where the believers assemble for prayers, as well as for the spiritual upliftment is the respectable premise that should be utilised extensively for the changing of Muslim minds towards this worldly life.
