Word recordings: Quran.com

Every Qur'anic word played on its own, in the lessons and on the Concept pages, is Quran.com's (Quran Foundation) word-by-word recording of that word at its place in the Qur'an. The files are copied, unaltered, to our server for non-profit educational use; only the part of the file that holds the word is played. Their buttons say “Quran.com recording”.

Qur'an vocabulary

Rank, counts, roots and word forms are computed from the Quranic Arabic Corpus 0.4 and the Tanzil text. Ayah translations are from QuranEnc. Word meanings were written with AI (Claude) from the cited ayat, using the QuranEnc and Saheeh International translations, then checked by AI. These meanings do not yet cite a kitab. Each word's sound: Quran.com / Quran Foundation's word-by-word recording of one place where the word occurs in the Qur'an. Unaltered copies are on our server. The tests in the step-by-step path are built by rule from the same data. We only count numbers: how many browsers open each section, how many visits arrive from the main Dakwah-Lens site, and how many times each test is tried and passed, with no name, account or IP address.

The narrator's voice (AI)

The explanations (ElevenLabs, eleven v3) are made with AI from the voice of the narrator Kang Nandar. The same AI voice (ElevenLabs, multilingual v2) also voices what has no word recording: parts of words (such as bi- or -hum), letters, practice forms not written in the Qur'an, and runs of several words. Their spelling is adjusted where needed so they are read correctly, and every one of those recordings was listened to before it was used. Their buttons say “AI voice”. These are not recordings of the imam.

The imam's recitation on the lesson pages

Every ayah is played from these recordings, with a timing for every word. They come from EveryAyah (everyayah.com) and are copied, unaltered, to our server for non-profit educational use:

• Recitation: Mishary Rashid Alafasy via EveryAyah.com · Word timings: Collin Fair, quran-align (CC BY 4.0)

Data versions

For technical checks: the version and file fingerprint (sha256) of every dataset the lesson pages use, exactly as recorded when the lessons were built.
