It is one of the largest mosques in Indonesia. The mosque has influences from various architectural styles: Malay, Turkish, Arabic, and Indian.
Construction on the mosque was completed on 20 October 1968. It was inaugurated by Arifin Achmad, the Governor of Riau. In 2000, it was renovated during the time of Governor Saleh Djasit, with its area being tripled from 4 hectares to 12.6 hectares. Due to the renovation, the Hang Tuah football stadium was demolished.
The mosque was once a campus for the Faculty of Usul al-Din State Institute of Islamic studies (IAIN) Sultan Syarif Kasim Pekabaru from its founding until 1973. IAIN Sultan Syarif Kasim State Islamic University is now the Sultan Syarif Kasim (UIN SUSKA) Pekanbaru.
