Traveling north into upper An Giang along National Highway 91C beside the west bank of the Hậu River, near the freshwater expanse of Búng Bình Thiên lake, visitors pass hamlets of high wooden stilt houses with boats moored along the bank and handlooms set directly beneath the house stilts. Rising above that low roofline stands a large, bright-walled building with pointed-arch windows, a central roof dome, and a crescent moon embracing a star high overhead. The building is large enough to be spotted from afar across the riverine borderland.
Inside, the prayer hall is kept open and uncluttered. There are no statues, no figurative paintings, no altar, no incense burner, and no ritual offerings. There are only a level tiled floor, geometric patterns along the walls, and a recessed niche set into the main prayer wall. That niche points toward Mecca, and the entire building is oriented to serve that single purpose. This is Jamiul Muslimin Mosque of Đồng Ky Cham village.
IA Cham village on the west bank of the Hậu River in An Phú
To state matters clearly from the start, as this is often conflated in general accounts, this is a mosque of orthodox Sunni Islam belonging to the Cham Islam community of the southwestern Mekong Delta. It is not a Bàni mosque. The Cham community in this border region has practiced orthodox Sunni Islam from the outset, observing five daily prayers, fasting throughout the month of Ramadan, and keeping their mosque open every day of the year.
The name Jamiul Muslimin comes from Arabic, in which jami denotes a congregational masjid where the community gathers for the Friday midday prayer, and muslimin means the Muslim believers. Together, the name describes the exact role of the building as the assembly place of the entire local community. Community records sometimes abbreviate the name as Masjid Al Muslimin, while geographical survey papers transcribe it in separated syllables as Jamiul Mus Li Min. All three forms refer to this single mosque in Đồng Ky hamlet (also spelled Đồng Ki in press reports, and known in the Cham language as Kaoh Khi-a or Koh Kagia, meaning Hopea Tree Islet after the sao trees that once grew abundantly here).
One point of potential confusion regarding the name should be noted, namely that another well-known mosque in Ho Chi Minh City is also named Jamiul Muslimin, the mosque of the Cầu Kho Cham neighborhood on Trần Hưng Đạo Street, for which the library has a separate entry. The two mosques share a common Arabic name widely used across the Islamic world, but are two completely separate institutions.
According to Islamic doctrine, the foundation of faith is belief in the One God, who has no physical form and cannot be depicted in images. Consequently, the mosque contains no statues, no paintings of people or animals, no incense burners, and no ritual offerings. Interior decoration consists solely of geometric patterns and calligraphic verses from scripture.
The duties of a believer rest on five pillars, namely the declaration of faith, prayer five times a day, fasting throughout the month of Ramadan, almsgiving, and the pilgrimage to Mecca for those who have the means. In orthodox Sunni Islam, these five observances are the personal obligation of each individual believer and cannot be delegated to a proxy, which is why the mosque remains open year-round with worshippers attending daily.
The main lower prayer hall is reserved for men. In this mosque, the prayer space for women is built as a permanent mezzanine level above, rather than a side curtain or later annex. This structural layout is noteworthy because it shows that the builders designed dedicated space for both men and women within the main frame from the outset. Religious affairs in the mosque are overseen by a board of community officials headed by the Hakim, together with the Imam who leads prayer, the Khatib who delivers the sermon, and the Bilal who calls the congregation to prayer.
In Vietnam, the term Islam (Hồi Giáo) is used broadly for two streams whose actual practice differs so substantially that they cannot be described as one, and the library summarizes that contrast here for reference.
Orthodox Islam, the stream to which Jamiul Muslimin belongs, assigns the five pillars to each individual believer. The mosque opens year-round for the five daily prayers, the Friday midday service brings the whole congregation together, the entire community fasts throughout the month of Ramadan according to the Hijri lunar calendar, and the pilgrimage to Mecca is undertaken when means allow.
Bàni Islam of the Cham in the former Ninh Thuận and Bình Thuận provinces is a localized tradition that has blended with indigenous beliefs, Cham custom, and an earlier Brahmanical layer. Bàni entrusts the observance of the five pillars to a clerical class on behalf of the lay community, maintains ancestral veneration rites, observes the holy month of Ramưwan according to the Cham calendar, and opens its sanctuaries only during ritual seasons. Both streams trace back to a shared origin but have followed two distinct paths for centuries. The library records this distinction as an empirical fact, without ranking one above the other.
Two common points of confusion should be clarified in an objective tone, without fault-finding.
First, administrative boundaries changed in 2025 and are easy to mix up. Đồng Ky hamlet formerly belonged to Quốc Thái commune (situated along the west bank of the Hậu River, just east of Búng Bình Thiên lake). Following the 2025 administrative reorganization, Quốc Thái commune, Nhơn Hội commune, and part of Phước Hưng commune were merged under the shared name of Nhơn Hội commune. Consequently, the mosque's current address is listed under Nhơn Hội commune according to the new boundaries. Visitors should be careful not to confuse it with Khairiyah Mosque (Al Khairiyah) in Búng Lớn hamlet, which belonged to the former Nhơn Hội commune on the western side of Búng Bình Thiên lake and along the Bình Di River. Both mosques now fall within the expanded Nhơn Hội commune, but they are two completely separate mosques in two different hamlets.
Second, calling this building a Cham pagoda (chùa Chăm) is inaccurate. The Vietnamese word chùa refers to a Buddhist temple with Buddha statues and monastics. Here there are no statues, no monastics, and no altar. That phrase is merely a casual way outsiders give directions and is not used by the community itself.
IIFrom 1933 to the present building
The history of this mosque is the story of a single site rebuilt multiple times over nearly a century. What has remained constant across every reconstruction is not the physical building, but the ground it stands on and its orientation toward Mecca. In keeping with the standards of the Places section, the library records only the milestones belonging to construction history and religious life.
- 1933First mosque erectedThe Cham community in Đồng Ky village (known in Cham as Kaoh Khi-a, or Hopea Tree Islet) established their first congregational mosque on the strip of land along the Hậu River. This founding year is recorded in reports by Thanh Niên newspaper and Voice of Vietnam.
- 1984Rebuilt on the original siteThe community reconstructed the mosque on the original plot and used that building for more than twenty years. By the early 2000s, the structure had deteriorated and could no longer accommodate the growing congregation.
- April 7, 2008Groundbreaking of the present buildingConstruction of the new mosque began on the same site on a much larger scale than previous structures.
- December 3, 2009Inaugurated on Raya Idil AdhaThe Representative Board of the Islamic Community of An Giang province held the inauguration ceremony coinciding with the Raya Idil Adha festival (1430 AH), completing the project at a total cost of 5.58 billion VND (rounded to 5.8 billion VND in some local accounts).
- During the 2008 to 2009 constructionDomestic and international fundingFunding came from contributions by Muslim believers in Vietnam and abroad, together with a grant of 147,000 USD from the Red Crescent Authority of the United Arab Emirates (UAE).
- 2019Community demographic figuresThe Cham Islam population in An Giang was recorded at over seventeen thousand people concentrated across nine commune-level units, including the Đồng Ky settlement.
- 2025Administrative boundary mergerFollowing the 2025 administrative reorganization, Quốc Thái commune, Nhơn Hội commune, and part of Phước Hưng commune merged to form the new Nhơn Hội commune.
The most notable historical detail documented for this building is its funding structure. According to a December 4, 2009 report in Thanh Niên newspaper, the total construction cost of the new mosque was 5.58 billion VND, of which the Red Crescent Authority of the United Arab Emirates sponsored 147,000 USD, while the remainder was contributed by Muslim believers within Vietnam and overseas.
That combination of resources illustrates an important aspect of the Cham Islam communities of the Mekong Delta, namely their ability to maintain ties with the wider Islamic world while preserving the close-knit fabric of a riverside delta village. A rural hamlet whose residents make their living from weaving, embroidery, livestock raising, and small trade near the upstream border was able to erect a five-billion-dong congregational hall because support came simultaneously from local hands and transnational religious charity.
IIIThe lower hall, mezzanine, and mihrab
What distinguishes this building from most other village mosques in the delta is its two-level structure. Village mosques in the region typically consist of a single ground-floor hall. Here, the lower prayer hall serves men, while an integrated upper mezzanine level serves women as part of the primary structural design rather than a later addition. This layout greatly expands the building's capacity, allowing up to a thousand worshippers to attend services simultaneously while observing the religious separation of prayer spaces.
A wide, open hall with a level tiled floor, no pews, no statues, no paintings, and no altar. Worshippers stand shoulder to shoulder in horizontal rows. This main lower floor is reserved for men.
The upper gallery built integrally into the structure overlooking the main hall, reserved for women. This arrangement allows women to participate in congregational services while maintaining the customary separation of prayer spaces.
A recessed niche set into the main prayer wall, marking the qiblah direction toward Mecca. The mihrab is neither an altar nor a shrine for sacred objects, serving solely to orient the congregation.
A stepped pulpit placed beside the mihrab, used for delivering the sermon during the Friday midday service. It is the only raised structure in the hall, elevated for practical function rather than clerical rank.
A water tank and row of taps near the entrance used for the obligatory ritual washing before each prayer service, performed in sequence from hands, mouth, nose, and face to forearms, head, and feet.
The central roof dome and tall minaret tower used for announcing the call to prayer. Atop the dome sits a crescent moon embracing a five-pointed star, the unmistakable silhouette of a masjid from afar.
For visitors accustomed to Vietnamese communal houses and Buddhist temples, one structural contrast is immediately apparent, namely the absence of a multi-layered longitudinal axis. Traditional Vietnamese temples lead visitors through a triple gate, courtyard, front hall, and enclosed inner sanctuary that grows progressively more private and sacred. A mosque opens directly from the courtyard and ablution taps into a single wide room. No part of the room is more enclosed than another because there is no sacred object stored inside. The only spatial division here is between the standing areas for men and women, organized vertically by floor level rather than longitudinally by depth.
Interior decoration adheres strictly to Islamic doctrine, consisting solely of geometric patterns, stylized floral motifs, and calligraphic verses from scripture, without a single depiction of people or animals. To eyes accustomed to temples filled with statues and horizontal lacquered plaques, the prayer hall at first appears empty, yet that openness is intentional and forms the core architectural expression of the mosque.
IVThe lie of the land and orientation
An explicit qualification is needed at the start of this section. Islam does not teach feng shui. The orientation of a mosque is governed by a single mandatory rule of the faith, the qiblah direction pointing toward the Kaaba in Mecca along the shortest path across the globe. From this southwestern border region, that bearing falls slightly north of due west. The builders have no discretion to choose otherwise. No geomantic compass, no founder's birth year, and no astrological trigram play any role in selecting that alignment, and if a plot of land lies at an angle, worshippers align their prayer rows toward Mecca rather than shifting the qiblah.
The commentary below is a traditional Vietnamese geomantic reading offered by the library purely as a comparative reference for readers familiar with East Asian siting principles, not a teaching of Islam or a consideration of the local community when building the mosque.
First is the single-direction principle itself. Traditional feng shui determines a building's orientation according to the lie of the land, water flow, and the householder's birth destiny, so each temple takes a different direction. Islam operates on the opposite premise, whereby every mosque across the earth turns toward the same focal point regardless of the local plot on which it stands. Viewed through traditional geomantic eyes, this is an external-center system whose reference point lies thousands of miles beyond the site, a concept with no equivalent in classical geomancy.
Regarding the lie of the land, Đồng Ky village sits on flat alluvial ground along the west bank of the Hậu River (within the An Phú river island bounded by the Hậu River to the east, the Bình Di River to the west, and the freshwater expanse of Búng Bình Thiên lake nearby), without any hill or elevation behind it and subject to the annual flood season. In lowland geomancy, where mountains are absent, watercourses stand in for mountain dragon veins, with flowing currents conducting qi and natural lakes or ferry landings gathering qi. A major river running close by alongside a large natural lake represents a configuration of prosperous water (thủy vượng). Its advantage is an abundant influx of qi, while its challenge is that qi can easily be swept away by the current, a challenge classical lowland siting resolves by erecting an enclosed rectangular structure buffered by an open front courtyard acting as a small bright hall (minh đường). The mosque compound here happens to match that layout, though not for geomantic reasons.
Regarding structural form, a five-phases reading sees the rounded dome on the roof as a curved form belonging to Metal, while the tall minaret tower beside it rises as a vertical stroke belonging to Wood. Metal at the center and Wood standing alongside form a pair that classical manuals examine closely because Metal overcomes Wood. Again, the dome and call-to-prayer tower are long-standing conventions of Islamic architecture that predate and stand completely independent of East Asian five-phases theory. The library notes this contrast not to judge auspiciousness, but to show how two traditions read the same physical form through two entirely different vocabularies.
Finally, there is the two-level hall. Classical Vietnamese geomancy reads a house of worship along a horizontal axis from the outer gate to the deepest sanctuary, tracking how qi progresses through successive thresholds. Here there is no such longitudinal progression, only a single wide room stacked in two levels where the spatial division reflects congregational modesty between men and women rather than degrees of sacrality. Classical geomantic manuals have no category for a house of worship divided vertically for that purpose, and the library records that structural difference plainly as it is.
VDaily, weekly, and annual observances
The liturgical rhythm of the mosque unfolds in three layers, consisting of five daily prayers, the Friday congregational prayer, and annual festivals calculated by the Hijri calendar, the lunar calendar of Islam. Because the Hijri year is roughly eleven days shorter than the solar year, Islamic observances move gradually across the seasons. In a riverside village like Đồng Ky, that means the fasting month of Ramadan falls in the middle of the dry season in some years and during the annual flood season in others.
| Time in the Hijri calendar | Observance | Description |
|---|---|---|
| Daily | Five daily prayers | Five prayer times determined by the position of the sun throughout the day. Worshippers must perform ritual ablution with water at the entrance before each service. |
| Every Friday | Jumu ah prayer | The principal congregational service of the week at midday, featuring a sermon delivered from the minbar followed by prayer in rows. This is the service where both the lower hall and the upper mezzanine are filled. |
| 12th day of Rabi al-Awwal | Maulid | Commemoration of the birth of the Prophet Muhammad, listed in studies of the An Giang Cham community as one of the three major annual observances. |
| Entire month of Ramadan | Month of fasting | The ninth month of the Hijri calendar. Believers abstain from food and drink from dawn until sunset, gathering at the mosque in the evening to break the fast and offer night prayers. |
| 1st day of Shawwal | Roya Idil Fitri | The festival marking the end of the Ramadan fast, known internationally as Eid al-Fitr. The community gathers at the mosque for morning prayer before visiting relatives and tending family graves. |
| 10th day of Dhul Hijjah | Roya Haji | The festival of sacrifice, known internationally as Eid al-Adha (also written Raya Idil Adha), coinciding with the pilgrimage to Mecca. Livestock is slaughtered and shared among community households and those in need. |
Beyond ritual prayer, the mosque maintains two ongoing responsibilities standard to any masjid, namely Qur'anic instruction for children in the hamlet and charitable giving, which includes both the obligatory annual alms known as zakat and voluntary offerings known as sadaqah.
Daily life in the village closely follows religious norms, including halal dietary rules, abstention from alcohol, and modest dress with headscarves for women. Most families in the village make their living through brocade weaving, embroidery, livestock raising, and small trade around Đồng Ky market, with many households setting up their looms directly beneath their stilt houses. The large mosque standing in the center of the hamlet is therefore not a monument detached from everyday life, but the shared house into which the village pooled its savings and labor, and to which residents return five times every day.

This is an active house of worship, so visitors should observe local religious customs. Remove shoes before stepping into the prayer hall. Dress modestly, with men wearing long trousers and sleeved shirts, and women covering their hair with a headscarf and wearing clothing that covers arms and legs. The lower prayer hall is reserved for men and the upper mezzanine level for women. Do not walk directly in front of anyone who is praying, speak loudly, or photograph worshippers during services. Friday midday is the most crowded service of the week, so visitors coming to view the architecture should wait until the prayer has concluded.
