At the time, the total number of Muslim residents of Yishun stood at 102 individuals.

Local Muslim residents from Yishun and the surrounding villages met to form a Mosque Building Committee.

With support from the Islamic Religious Council of Singapore (Muis), funds began to be raised for the construction of the mosque.

Several names for the new mosque were suggested such as AI-Jannah, AI-Makmur, Assobirin, Faisah, AI-Bilal, AI-Muaasim, Aminin, AI-Syuhadah and AI-Araf, but the Fatwa Committee's final verdict was Darul Makmur.

[2] Alhamdulillah, with the conscientious efforts, contribution, and support of the Mosque Building Committee and Muslim residents in Yishun and nearby areas, Darul Makmur Mosque construction was completed and officially launched on 25 July 1987.
