[2] The mosque was commissioned by the late Sultan Salahuddin Abdul Aziz, when he declared Shah Alam as the new capital of Selangor on 14 February 1974.

[2] The four minarets, each reaching 142.3 m (467 ft) above ground level,[4] are the third tallest in the world, after those at the Hassan II Mosque in Casablanca, Morocco,[5] and the Djamaa el Djazaïr in Algiers, Algeria.

The dome is constructed of aluminium and the outer surface is clad with vitreous enamel-baked triangular steel panels decorated with a rosette of verses from the Qur'an.

The main prayer hall spans two levels, is fully carpeted and air conditioned, and is one of the largest such spaces in the world.

These 14 hectares of spiritual sanctuary house nine galleries exhibiting a rich array of Islamic arts such as calligraphy, sculptures, paintings, and architecture.
