The Rahmatan Lil 'Alamin Mosque was recently established on the UIII campus in 2021 inside the Three Pillars Plaza as a means of offering the Muslim community at UIII a place to worship and socialize. The Mosque welcomes all Muslim students, staff, professors, and Muslims from the surrounding areas.

Being one of the Pillars at the Three Pillars Plaza, the mosque itself is unique by design and welcomes up to 1500 people where its first floor is for the male Muslim worshippers, while the second floor is designated for the female worshippers.
