The students’ residential colleges in IIUM are also known as Mahallah, which is Arabic for ‘neighbourhood’. IIUM’s mahallahs are self-contained not only with services but also activities, and are named after the leading companions of the Prophet s.a.w and the female Mujahidah and Syuhada.
Since the early years of its establishment, IIUM has practiced 100% accommodation for its full time undergraduate students. For postgraduate students, accommodation is provided based on availability of rooms. Priority is given to the non-Malaysian students, especially students from the newest intake.
Currently, IIUM has 16 mahallahs that accommodate about 14,000 students from various countries and cultures. Each mahallah is lead by a Principal and assisted by administrative staff and fellows. The staff concentrates on the administrative and maintenance needs of the mahallah, while the fellows focus on students' matters and activities.
