Driving along the coastal highway through the Al Ghubrah district in western Muscat, visitors see a sand-colored minaret rising above the tree line, taller than every surrounding roof. Beyond the gates lie trimmed gardens, long pointed-arch arcades of pale stone, and marble paving that stays cool underfoot even under the fierce coastal sun. Stepping into the main prayer hall, newcomers usually pause at two sights: the hand-woven carpet stretching across the entire floor and the crystal chandelier suspended beneath the central dome.
Oman is the only country in the world where the majority of Muslims follow the Ibadi school, alongside Sunni and Shia communities. The library selected this site as the sole entry for Oman because it serves as the principal congregational mosque of the entire country, where Friday prayers and the two Eid festivals gather the largest congregations, and because it houses an Islamic library and study complex within its grounds. Though a contemporary work, it offers a clear window into Islamic life in Oman today.
IThe National Congregational Mosque of an Ibadi-Majority Country
The English term grand mosque corresponds to the Arabic concept of a jami, a congregational mosque that hosts the collective Friday midday prayer and sermon, distinct from smaller neighborhood or village mosques. The monument bears the name of the sultan who commissioned it.
According to Mosques of the World, the design was chosen through an international architectural competition in 1993 won by the Iraqi architect Mohammed Saleh Makiya together with Quad Design of London. Because the grounds combine prayer halls with a library, an Institute of Islamic Sciences, an information center, and a lecture hall, the complex functions as both a house of worship and a place of learning.
Ibadi Islam is a distinct branch of Islam tracing its roots to the early centuries of the faith, differing from both Sunni and Shia traditions on certain points of jurisprudence and on the selection of community leadership. Worshippers read the same Qur'an, pray five times daily, and face the same direction toward Mecca. As the national congregational mosque, the sanctuary welcomes Muslims of all schools to pray side by side. The library notes these points for orientation without judging between traditions.
According to Mosques of the World, the five minarets of the complex symbolize the Five Pillars of Islam: the declaration of faith in the one God and the Prophet Muhammad, the five daily prayers, almsgiving, fasting during the month of Ramadan, and the pilgrimage to Mecca once in a lifetime for those who are able.
A common misconception: because visitor numbers are high and the building is relatively new, some assume it is primarily a tourist landmark. It is not. This is an active mosque holding five daily prayers, Friday congregational prayers, and Eid services in its main and women's prayer halls. Non-Muslim visitors are admitted only during designated morning visiting windows outside prayer hours.
The label largest is also frequently overstated. According to the carpet specialist Nazmiyal, the prayer carpet here held the record as the largest single-piece hand-woven carpet in the world until 2007, when it was surpassed by the carpet in Abu Dhabi, leaving Muscat's carpet in second place. In capacity and area, the mosque is the largest in Oman, though smaller than several other grand mosques in the wider region.
Belonging to the same generation of contemporary Gulf grand mosques is the Sheikh Zayed Grand Mosque in Abu Dhabi, begun a few years later. Both are celebrated for monumental carpets and chandeliers, yet Abu Dhabi employs white marble cladding and scores of domes, whereas Muscat maintains a warm sand-colored sandstone palette and a single central dome. The entry on Abu Dhabi discusses Gulf carpets and chandeliers in general, while this entry records the specific figures for Muscat.
IIFrom the Design Competition to Inauguration Day
The history of a contemporary monument is brief and well documented, with only minor variations among sources regarding the start date of construction. The milestones below trace its design, construction, and inauguration.
- 1993International design competitionFollowing the project announcement in 1992, an international competition in 1993 selected the design by Iraqi architect Mohammed Saleh Makiya and Quad Design of London, according to Mosques of the World.
- 1994Construction begins according to one sourceMosques of the World records that construction began in December 1994 under the contractor Carillion Alawi. See the source note below regarding 1995.
- 1995Construction begins by another calculationOman Views states that the mosque took six years to build, which, counted back from the 2001 opening, places the start around 1995.
- Four yearsWeaving the carpet and crafting the chandelierThe prayer hall carpet was woven over four years by 600 Iranian weavers of the Iran Carpet Company (ICC) according to Mosques of the World. Nazmiyal records roughly 500 to 600 weavers working in two shifts in Nishapur (Neyshabur), Khorasan Province. The crystal chandelier was likewise crafted over four years by Faustig in Germany.
- 2001InaugurationOn May 4, 2001, the mosque was officially inaugurated after six years and seven months of work, according to Mosques of the World.
The sources consulted by the library differ on five figures, and both sides are recorded here. Start of construction: December 1994 according to Mosques of the World, whereas Oman Views states six years of construction before 2001, implying roughly 1995. Area: 416,000 square meters according to Mosques of the World, versus 40,000 square meters according to Oman Views. Architectural documentation confirms that 416,000 square meters represents the total site area including gardens and outer grounds, while roughly 40,000 square meters is the built footprint of the complex.
Capacity: about 20,000 worshippers according to Mosques of the World, and 22,000 according to Oman Views. Prayer carpet: Mosques of the World gives approximate dimensions of 70 by 60 meters (alongside the exact area of 4,343 square meters) and a weight of 21 tons, Oman Views states over 4,200 square meters, and Nazmiyal gives exact dimensions of 70.50 by 60.90 meters, about 4,343 square meters, weighing 22 tons. Chandelier: 8,500 kilograms according to Mosques of the World, and 8 tons according to Oman Views. The latter two differences reflect rounding conventions across sources.
IIISand-Colored Sandstone, the Central Dome, and Five Minarets
According to Mosques of the World, the exterior is clad in roughly 300,000 tons of Indian sandstone, while the interior combines marble from India, Oman, Italy, and Egypt with doors carved from Burmese teak. The resulting palette is warm sand on the outside and cool white and pale gray within, well suited to the bright Omani coast. The square main prayer hall is crowned by a central dome rising 50 meters above the floor on four piers, with the crystal chandelier suspended beneath its apex.
The complex is enclosed by walls and flanked along its northern and southern sides by two long arcaded corridors (riwaq), each stretching 240 meters and divided into halls decorated in Andalusian, Persian, Egyptian Mamluk, Syrian, and Omani styles. Within stand two prayer halls: the main prayer hall for men holding 6,500 worshippers, and a separate women's prayer hall holding 750 worshippers according to Mosques of the World. Paved outer grounds accommodate another 8,000 worshippers alongside the inner courtyards and galleries, bringing total capacity across the complex to roughly 20,000 during major feasts.
Standing 91.5 meters high according to Mosques of the World, it serves as a visual landmark across the coastal plain of Muscat.
Each rising 45 meters at the four corners of the complex. Together with the main tower they form five minarets symbolizing the Five Pillars of Islam.
Rising 50 meters from the floor of the main prayer hall according to Mosques of the World, with an interior lined with porcelain panels, timberwork, and Thuluth calligraphy.
Hand-woven in 28 vegetable-dyed colors with 1.7 billion knots by roughly 500 to 600 Iranian weavers over four years, drawing on classical Tabriz, Kashan, and Isfahan designs. Mosques of the World gives roughly 70 by 60 meters (4,343 m², 21 tons), while Nazmiyal gives 70.50 by 60.90 meters (4,343 m², 22 tons).
Measuring 14 meters tall and 8 meters wide, with a 24-carat gold-plated frame set with over 600,000 Swarovski crystals and 1,122 halogen lamps according to Mosques of the World, weighing 8,500 kg and crafted by Faustig (Germany) over four years.
A three-story library holding between 20,000 and 30,000 volumes, alongside the Institute of Islamic Sciences and a 300-seat lecture hall, according to Mosques of the World and Oman Views.

IVLandform and Orientation
This section is included because many Vietnamese readers are accustomed to reading sacred sites through landform, but a clear caveat comes first: Islam, whether Ibadi, Sunni, or Shia, does not practice geomancy (feng shui). The orientation of a mosque follows a single rule, the qibla, which aligns the mihrab wall toward the Kaaba in Mecca. From Muscat, Mecca lies nearly due west, slightly south of west, and the entire complex is laid out along that axis.
The landform reading below is offered by the library through a traditional Vietnamese lens for comparison. Neither the architect nor the mosque's documentation describes the site in these terms.
The broadest feature is mountains behind, sea in front in a regional sense. Muscat occupies a narrow coastal plain wedged between the rocky Hajar Mountains to the south and the Gulf of Oman to the north. The mosque stands on the level floor of that strip. Traditional Vietnamese geomancy calls a setting backed by mountains on one side and open to water on the other "backed by mountain, facing water", and on a map the city of Muscat as a whole fits that pattern.
Yet the orientation of the building itself does not follow the mountain-to-sea axis. Because the qibla points west, the prayer hall backs onto the west while the main approach opens from the east. Read in Vietnamese terms, the complex sits west and faces east, running parallel to the coastline rather than facing the sea. That contrast highlights the difference between the two traditions: Vietnamese geomancy aligns buildings with local rivers and peaks, whereas a mosque aligns with a focal point thousands of kilometers away.
Second is the main minaret. Rising 91.5 meters, the tower stands far above every surrounding structure. Traditional geomancy compares a solitary tall shaft on a flat plain to a brush-tip peak (văn bút) or anchoring pillar that gathers the eye. The architect erected five minarets to represent the Five Pillars of Islam, so the visual parallel with geomancy is purely formal.
Finally, there are the gardens in an arid land. Muscat's climate is hot with scant rainfall. Read through the Five Phases, the green lawns and trees within the enclosure represent Wood nurtured amid Earth and Fire. Readers accustomed to humid landscapes will see in these gardens the result of deliberate care rather than effortless natural abundance.
VCongregational Prayers and Feasts of the Hijri Calendar
All religious observances at the mosque follow the Islamic Hijri calendar, a purely lunar reckoning whose year is roughly eleven days shorter than the solar year. Consequently, the month of Ramadan and the two Eid festivals shift backward through the solar seasons each year. Mosques of the World notes that the complex holds about 20,000 worshippers during major gatherings such as the Eid prayers and busy Fridays. This entry records calendar dates without listing daily clock hours.
| Observance | Calendar reckoning | Description |
|---|---|---|
| Five daily prayers | Daily, timed by the sun | Dawn, midday, afternoon, sunset, and night prayers held in the men's and women's prayer halls. |
| Friday congregational prayer | Weekly | Midday congregational prayer accompanied by a sermon (khutbah), when the main prayer hall is fullest each week. |
| Month of Ramadan | Hijri calendar, ninth month | Fasting from dawn to sunset, with additional evening prayers (tarawih) and the largest crowds during the final ten nights. |
| Eid al-Fitr | Hijri calendar, 1st of Shawwal | Festival marking the end of the Ramadan fast, beginning with morning congregational prayer across the filled complex. |
| Eid al-Adha | Hijri calendar, 10th of Dhu al-Hijjah | Festival of Sacrifice coinciding with the Mecca pilgrimage season, marked by morning prayer and the sharing of meat with those in need. |
The library has not found documentation regarding Vietnamese community activities in Muscat or at this mosque and therefore records none.
