Jadhr is built on other people's careful work. Here is whose, and under what terms.

Qur'an text: the Tanzil Project

The Uthmani text shown on the āyah card is checked, character for character, against the Tanzil Quran Text (Uthmani, Version 1.1), Copyright © 2007–2026 Tanzil Project, licensed under the Creative Commons Attribution 3.0 licence. Source: tanzil.net.

“Permission is granted to copy and distribute verbatim copies of this text, but CHANGING IT IS NOT ALLOWED.”

“This Quran text can be used in any website or application, provided that its source (Tanzil Project) is clearly indicated, and a link is made to tanzil.net to enable users to keep track of changes.”

“This copyright notice shall be included in all verbatim copies of the text, and shall be reproduced appropriately in all files derived from or containing substantial portion of this text.”

Jadhr shows each āyah whole and unaltered. Colouring the root letters is a display layer and does not change the text. The one word used in the Spot step is the same word in the Tanzil Quran Text (Simple, Version 1.1, imlāʾī spelling), © 2007–2026 Tanzil Project, CC BY 3.0, also reproduced unaltered. Track changes to the text at tanzil.net/updates.

How verses are chosen

Each root's āyah is chosen against written criteria, in order: the word must carry the root according to the Quranic Arabic Corpus (never a proper noun); the verse must show the sense being taught and read clearly without commentary; its register is mercy, guidance, worship, character, creation or reflection; a verse of punishment is never the reward; no Name of Allah is ever a puzzle clue or the word to find; one āyah serves one root; and well-known āyāt are preferred. Roots whose every occurrence is heavy stay out of the Daily, and the root of the Name of Allah is never a puzzle.

Every āyah is then machine-checked word by word: the Arabic must be Tanzil's text exactly and agree with the Quranic Arabic Corpus letter for letter, the cited word must carry its root, and the translation must be Pickthall's 1930 wording. The choices were drafted and checked with the help of an AI model (Claude) under the direction of Jadhr's maker. They have not had a separate scholarly review, and we do not claim one. Corrections are welcome at hello@jadhrdaily.com.

Roots and morphology: the Quranic Arabic Corpus

“This annotation can be used in any website or application, provided its source (the Quranic Arabic Corpus) is clearly indicated, and a link is made to http://corpus.quran.com to enable users to keep track of changes.”

Jadhr's root and word-family data is derived from the corpus and modified by Inheriting Islam (2026): roots and families were extracted, and transliteration added. That data file is itself licensed under the GNU GPL v3 and is served in full, unminified, at /play/content.mjs.

Translation: Pickthall

English translations of each āyah are from Marmaduke Pickthall, The Meaning of the Glorious Koran (1930). It is in the public domain in the United States (since January 1, 2026) and in the United Kingdom and European Union.

Fonts

Jadhr serves its own copies of three typefaces, all licensed under the SIL Open Font License 1.1. They are subset to the characters Jadhr uses and converted to WOFF2, which the licence allows; none declares a Reserved Font Name. Each licence is served beside the fonts.
