Masjid Sabireen was established in 1998 by the Cham American Muslim Community. Cham people are an ethnic minority from Vietnam and Cambodia. Masjid Sabireen originally started with only a handful of Cham families that moved from Orange County to Pomona to be near the newly acquired Masjid. Alhumdulillah, the masjid has been blessed with new members and a growing community from various backgrounds each year. Today, it is a 501c3 Non Profit serving the local muslim community in the Pomona Valley.
