The Saidina Abu Bakar As Siddiq Mosque (MSABA) is a prominent mosque in Bangsar, Kuala Lumpur, Malaysia. The mosque was named after Muhammad‘s successor (Caliph) Abu Bakr. It is amongst the earliest classic examples of a postmodern mosque in Malaysia. Nestled in the urban suburb of Bangsar in Kuala Lumpur, the mosque represents the pan- Islamic style that is heavily influenced by the Mughal and Arabian architectural typologies, designed to suit the local vernacular language in a modern manner. The mosque’s construction was initiated by the local Muslim residents in Bangsar of around 3,500 people living and working in the surrounding areas in 1976.

The architecture is of traditional Malay mosque architecture with a minaret (43.3 m), arches, dome (16.6 m wide and 24 m from the floor), and motifs, but modern in form. It has an open concept, where air flow is allowed into the mosque as the door are made from hard wood. Islamic patterned holes are carved in between the motifs.

Its architectural designs are used in the construction for the Maldives National Mosque

The square layout plan of the prayer hall is based on the traditional Mughal model; despite the lack of a courtyard, it has a wide overspill prayer area and staircase access from various sides of the building. On the first floor is the female prayer gallery, while the ground floor accommodates the entrance area, ablution facilities, classrooms, office spaces and a library. The main prayer hall is naturally illuminated and ventilated through the stained-glass windows and the sliding screen doors. The cube form is strengthened with the exposed dome support structures and pointed mihrab niche, where the minbar is also placed. A pair of large Quranic tablets made out of timber is set symmetrically on the front qibla wall
