The mosque was completed in 1980 and is the fifth one built under the Mosque Building Fund (MBF) scheme. The chosen name Al-Muttaqin refers to the pious people who are ever aware of God the Almighty. Located in the central area of the Singapore island, the mosque serves the residents of Ang Mo Kio housing estate.
Recently, the mosque underwent an upgrading programme which was completed in 2017. Today, besides being a prayer house, the mosque also offers part-time religious classes (madrasah) and kindergarten classes as well as social development services for those in need.
