IslamRus

IslamRus (islamrus) is a multi-portal Russian corpus of Islamic web discourse. The data were collected in December 2025 and January 2026; the current index was compiled in January 2026. Public subcorpora are provided by genre (doc.genre) and by portal (doc.portal).

Sources (portals)

IslamRus combines three analytical layers of Russian Islamic discourse: institutional communication (muftiate register), editorial media writing (news and commentary), and educational/advisory writing (didactic texts and Q&A). Portal labels correspond to doc.portal.

Portal coverage (current index)

Token coverage is intentionally uneven: the index is built around large media sources and then complemented with smaller educational and institutional components to maximize register diversity.

Reach (where available)

Audience figures are heterogeneous across portals. Where explicit portal metrics or widely used third-party estimates are available, they are listed here as contextual information.

• islam-today.ru: Semrush estimate — 1.51M visits (February 2025 snapshot).
• umma.ru: portal-reported — about 400,000 unique users per month; over 1,000,000 views per month.
• islam.ru: Ahrefs estimate — about 29K monthly organic search traffic (March 2025 snapshot).

islamdag.ru

islamdag.ru is treated as a high-coverage media-and-advisory source with a strong regional anchor in Dagestan. The portal explicitly frames its work as religious education and as protection from pseudo-religious movements linked to extremist ideology.

islam.ru

islam.ru is treated as a large-scale media portal in the current index. It contributes substantial news and editorial discourse and functions as one of the backbone sources for mainstream Russian-language Islamic public writing in IslamRus.

islam-today.ru

islam-today.ru is treated as a federal-scale media source combining news reporting with explanatory and advisory genres. In its positioning statement, the portal links its ideological basis to traditions historically characteristic for Muslims of Tatarstan and Russia.

umma.ru

umma.ru is treated as an author-centered educational source in IslamRus. The site describes itself as an educational project, states a 1999 launch, and identifies Shamil Alyautdinov as the author of materials.

azan.ru

azan.ru is treated as a structured educational and reference source. A programmatic portal text frames the project as “traditional Sunni” in creed and madhhab-based jurisprudence and presents it as an educational initiative.

muftiyatrd.ru

muftiyatrd.ru is treated as the institutional component of IslamRus. It represents the public communication of the Muftiate of the Republic of Dagestan and is used to capture a formal, administrative register (announcements, statements, organizational texts).

Public subcorpora

Public subcorpora are provided by genre (doc.genre) and by portal (doc.portal). Genre subcorpora support controlled comparisons between editorial discourse, news reporting, and Q&A interaction.
