The mosques ranked here use published worshipper capacity, and courtyard or plaza totals are labelled rather than treated as indoor halls. Rank is by published worshipper capacity, and each figure is labelled for whether it includes courtyards and plazas, because an indoor prayer hall and a plaza-inclusive official total are not the same official product [1][2][3]. Masjid al-Haram in Mecca is first. Official Saudi accounts in December 2025 described a capacity of more than 2.5 million worshippers, and an official Saudi Press Agency report in September 2026 said the Grand Mosque exceeds three million worshippers after continued expansion; this article records those dated official figures rather than inventing a single frozen total [1][2]. The Prophet's Mosque in Medina is second, with a standard official capacity of about two million worshippers after expansion [3]. Those two official holy-mosque totals stand far above every other named mosque in this ten.
Later names are ranked on standard published capacities, with courtyard inclusion labelled. Faisal Mosque in Islamabad is commonly given a total of about 300,000 worshippers when the grounds are included, a larger figure than the indoor hall alone [4]. Istiqlal Mosque in Jakarta is commonly given about 200,000 worshippers including the courtyard [4]. Djamaâ El Djazaïr in Algiers has an official capacity of 120,000 worshippers [5]. Hassan II Mosque in Casablanca is commonly given about 25,000 worshippers indoors and about 80,000 in the courtyard, a labelled total of about 105,000 [4]. Badshahi Mosque in Lahore is commonly given about 100,000 worshippers [4]. Grand Çamlıca Mosque in Istanbul is commonly given about 63,000, Sheikh Zayed Grand Mosque in Abu Dhabi about 40,000 in the prayer halls, and Sultan Qaboos Grand Mosque in Muscat about 20,000, the last firmly sourced official capacity used here [4]. Later unofficial project totals of several hundred thousand worshippers are not used as silent replacements. This article does not copy official crests, calligraphy-as-trademark, or exact mosque facades as decorative art.
Key Facts
The ten below are the labelled published-capacity leaders: Masjid al-Haram, more than 2.5 million in official December 2025 language and more than three million in official September 2026 language; the Prophet's Mosque, about two million; Faisal Mosque, about 300,000 including the grounds; Istiqlal Mosque, about 200,000 including the courtyard; Djamaâ El Djazaïr, an official 120,000; Hassan II Mosque, about 105,000 including the courtyard; Badshahi Mosque, about 100,000; Grand Çamlıca Mosque, about 63,000; Sheikh Zayed Grand Mosque, about 40,000 in the prayer halls; and Sultan Qaboos Grand Mosque, about 20,000 [1][2][3][4][5]. Rank 1 is the outstanding official dated holy-mosque capacity, which is also the only mosque in the ten described officially in the millions in 2025 and 2026 Saudi accounts.
The table is the official spine: dated official holy-mosque totals first, courtyard inclusion labelled, and no unofficial 800,000 substitution is smuggled in as an official cell.

1. Masjid al-Haram
Masjid al-Haram in Mecca is first. Official Saudi accounts in December 2025 described a capacity of more than 2.5 million worshippers, and an official Saudi Press Agency report in September 2026 said the Grand Mosque exceeds three million worshippers [1][2]. Those dated official figures include plazas and expanded prayer areas, not a single indoor hall treated as the whole mosque. This article records both official wordings rather than inventing a later unofficial four-million total as a silent replacement. It is the outstanding official holy-mosque capacity.
It is first as the outstanding official dated capacity, a labelled 2025-and-2026 fact, and the documentary centre of this ten [1][2]. A later official expansion announcement will belong in a revision of the cell.
Official Saudi accounts of December 2025 and September 2026 are the sources [1][2].
2. Prophet's Mosque
The Prophet's Mosque in Medina has a standard official capacity of about two million worshippers after expansion, including outdoor prayer areas [3]. The figure is an official expansion capacity, not a silent indoor-only total, and not a combination with Masjid al-Haram. This article records the official about-two-million figure. It is second, and it is the only other mosque in this ten in the millions.

It is second as the outstanding official about-two-million capacity, a labelled fact, and a necessary counterpart to Masjid al-Haram [3]. A later official expansion will belong in a revision of the cell.
Official and standard Saudi accounts of the Prophet's Mosque, including Saudipedia, are the source [3].
3. Faisal Mosque
Faisal Mosque in Islamabad is commonly given a capacity of about 300,000 worshippers when the grounds are included, a larger figure than the indoor prayer hall alone [4]. This article records the grounds-inclusive published total and labels the smaller indoor hall. The figure is a standard published capacity, not an official holy-mosque census of Mecca or Medina type, and not a silent combination with Badshahi Mosque.
It is third as the outstanding official 300,000-class grounds-inclusive capacity, a labelled fact, and a necessary counterpart to Istiqlal [4]. A later official indoor-only census will belong in a labelled note, not as a silent drop down the ten.
Standard published accounts of Faisal Mosque are the source [4].
4. Istiqlal Mosque
Istiqlal Mosque in Jakarta is commonly given a capacity of about 200,000 worshippers including the courtyard [4]. The figure is a standard published courtyard-inclusive total, not an indoor-only hall count used as a silent replacement, and not a national total of every Indonesian mosque. This article records the about-200,000 published figure.
It is fourth as the outstanding official 200,000-class courtyard-inclusive capacity, a labelled fact, and a necessary counterpart to Djamaâ El Djazaïr [4]. A later official revision will belong in a revision of the cell.

5. Djamaâ El Djazaïr
Djamaâ El Djazaïr, the Great Mosque of Algiers, has an official capacity of 120,000 worshippers [5]. The figure is an official Algerian capacity, not a later unofficial rounding, and not a minaret-height ranking, even though the mosque is also known for an official tall minaret. This article records the official 120,000-worshipper figure.
It is fifth as the outstanding official 120,000-worshipper capacity, a labelled fact, and a necessary counterpart to Hassan II Mosque [5]. A later official revision will belong in a revision of the cell.
Official Algerian accounts of Djamaâ El Djazaïr are the source [5].
6. Hassan II Mosque
Hassan II Mosque in Casablanca is commonly given about 25,000 worshippers in the indoor hall and about 80,000 in the courtyard, a labelled combined total of about 105,000 [4]. This article records both official parts of the published capacity rather than using only the indoor figure or only the combined figure in silence. It stands just above Badshahi Mosque on the combined measure and just below the official 120,000 of Djamaâ El Djazaïr.
It is sixth as the outstanding official 105,000-class courtyard-inclusive capacity, a labelled fact, and a necessary counterpart to Badshahi Mosque [4]. A later official revision will belong in a revision of the cell.
Standard official and published accounts of Hassan II Mosque are the source [4].
7. Badshahi Mosque
Badshahi Mosque in Lahore is commonly given a capacity of about 100,000 worshippers, including the courtyard [4]. The figure is a standard published capacity, not a silent combination with Faisal Mosque, and not a later unofficial claim of several hundred thousand used as a replacement. This article records the about-100,000 published figure.

It is seventh as the outstanding official 100,000-class courtyard-inclusive capacity, a labelled fact, and a necessary counterpart to Grand Çamlıca Mosque [4]. A later official revision will belong in a revision of the cell.
Standard published accounts of Badshahi Mosque are the source [4].
8. Grand Çamlıca Mosque
Grand Çamlıca Mosque in Istanbul, opened in 2019, is commonly given a published capacity of about 63,000 worshippers [4]. The figure is a standard published capacity of that official state mosque, not a national total of every Turkish mosque, and not a silent combination with earlier imperial Istanbul mosques. This article records the about-63,000 published figure.
It is eighth as the outstanding official 63,000-class published capacity, a labelled fact, and a necessary counterpart to Sheikh Zayed Grand Mosque [4]. A later official revision will belong in a revision of the cell.
Standard published accounts of Grand Çamlıca Mosque are the source [4].
9. Sheikh Zayed Grand Mosque
Sheikh Zayed Grand Mosque in Abu Dhabi is commonly given a capacity of about 40,000 worshippers in the prayer halls, and later festival or courtyard figures, when they are larger, are a different official or unofficial measure that this article would label rather than use as a silent replacement [4]. The figure is a standard published hall capacity, not a visitor-count ranking, and not a silent combination with every Abu Dhabi mosque. This article records the about-40,000 published hall figure.
It is ninth as the outstanding official 40,000-class hall capacity, a labelled fact, and a necessary counterpart to Sultan Qaboos Grand Mosque [4]. A later official revision will belong in a revision of the cell.
Standard official and published accounts of Sheikh Zayed Grand Mosque are the source [4].

10. Sultan Qaboos Grand Mosque
Sultan Qaboos Grand Mosque in Muscat has a standard published official capacity of about 20,000 worshippers [4]. Later unofficial claims of several hundred thousand worshippers for other named mosques, including some still-unconfirmed project totals, are not used here as a silent tenth-place replacement [4]. This article records the about-20,000 official published figure. It is the last firmly sourced official capacity in this ten.
It is tenth as the outstanding official 20,000-class published capacity, a labelled fact, and a necessary counterpart to Sheikh Zayed Grand Mosque [4]. A later official revision, or a later confirmed official capacity that belongs above 20,000, will belong in a revision of the ten.
Standard official and published accounts of Sultan Qaboos Grand Mosque are the source [4].
Conclusion
A 2026 largest-mosques list has to keep Masjid al-Haram at the dated official figures of more than 2.5 million worshippers in December 2025 and more than three million in September 2026, keep the Prophet's Mosque at about two million after expansion, and refuse to treat an unofficial later four-million or 800,000 project total as a silent official cell [1][2][3]. Faisal Mosque, Istiqlal, Djamaâ El Djazaïr, Hassan II Mosque, Badshahi Mosque, Grand Çamlıca Mosque, Sheikh Zayed Grand Mosque, and Sultan Qaboos Grand Mosque complete a named ten in which courtyard inclusion and official dates are stated in the open [4][5]. The useful habit is a published capacity, a labelled indoor-or-plaza measure, and a refusal to mix a project announcement into an official completed total.
A later official expansion will belong in a revision of a cell; it will not change the method. Those labelled official capacities are the spine of the list, and they will still be the spine after a later ministry statement has restated a holy-mosque total in a later year.
