About & trust

1. 01Knowledge is never paywalledLessons, answers, adhkār, the Qaida, recitation feedback and print files stay free.
2. 02No ads and no data salesNo ad SDKs. Nothing about how you use Sabīl is measured unless you allow it. Prayer times are calculated on the phone.
3. 03What AI writes is marked, and it answers no questionsThere is never a chatbot muftī: search only finds entries and quotes them word for word. Two things in the app are written by machine, and say so wherever they are shown: the draft translations of the library, and the articles, whose words are written by AI and checked by AI until scholars review them. The Arabic texts, their meanings and their sources are never written by AI.
4. 04Two scholars sign every itemReviewer names and dates are shown. The corrections log is public.
5. 05Rights before codeA register of every text, translation and recitation. Nothing ships if we don’t know where it came from.
6. 06Parity across languagesEvery language version of an entry must match before release. A language that lags is marked, not hidden.
7. 07Non-political, no polemicsNo party politics and no attacks on other groups.
8. 08Built for shared Android phonesLogin is optional. Works offline and uses little data.

• You do not need an account. Without one, Sabīl does not know who you are.
• Your place, the prayers you mark, your counts and your reading are stored in this browser, and you can export or erase them in Settings.
• Prayer times, the qibla and the Hijri date are calculated on the phone. Without an account, your location is never sent to us. It is never sent to anyone else.
• Requests to Sabīl reach our server through Cloudflare, Inc., United States, a network that carries them for us. To do that it handles each request, including the internet address it comes from.
• If you choose to sign in, a copy of your record is kept on Sabīl’s server so that your other devices can have it: your reading and saved entries, the prayers and fasts you mark, and your settings, including the place you chose. Zakāt figures and today’s counts stay on the phone.
• Your email address is used to sign you in and for nothing else. Sign-in emails are delivered by Resend, a mail service, which sees the address in order to deliver them.
• If you erase your record while signed in, it goes from this phone and from your account. Your other signed-in devices keep their own copy and stop sending it: each asks you whether to erase it there too, keep it there signed out, or put it back in your account.
• You can delete your account, with everything the server holds about you, from the Account screen.
• The app loads no advertising, no analytics and no third-party scripts or fonts.

The print library is written and its scholarly review is in progress, so every title is marked “review pending” until two scholars have signed it. The meanings of the Qur’ān and the ḥadīth collections come from outside publishers and sources and are shown before that review, each marked as unreviewed. Lessons and answers are published only after it.

Every correction is logged publicly, with a target time to answer it.

Library

The 21 Sabīl print titles. The reading edition is generated from the print files themselves. English and Bengali are the library’s own editions. In every other language it is shown in a draft translation, made by machine from the Arabic and the English and not yet read by a scholar or a native editor: it is marked as a draft on every screen, the English is one tap away, and the meaning of a quoted verse of the Qur’ān is a published edition’s own wording.

Transliteration

In the library, the print titles’ own lines; where a text has none, or none in Bengali or Devanagari letters, a line worked out by rule from the Arabic’s vowel marks and marked as generated. In the Qur’ān, the English transliteration distributed by Tanzil, shown as it stands. Neither has been reviewed: where one differs from the Arabic, the Arabic is right.

Qur’ān

The Tanzil Project’s Uthmani text, version 1.1, unchanged and checked verse by verse every time the app is built. Meanings: the editions of the Encyclopedia of the Noble Qur’ān (QuranEnc.com) in thirteen languages, and Pickthall’s English (1930).

Ḥadīth collections

The Arabic of seven collections from the open hadith-api dataset, and that dataset’s own translations in six languages, shown as they stand. Their accuracy and rights are not yet verified.

Prayer times

The open-source adhan library, run on the phone.

Hijri dates

The Umm al-Qurā calendar built into the browser.

Explained ḥadīths

The Encyclopedia of Translated Prophetic Hadiths (HadeethEnc.com) in thirteen languages, shown as it stands under its terms for republication. Its grades name no grader, and Sabīl has not reviewed it.

Tajwīd colours

The quran-tajweed data by Collin Fair, under the Creative Commons Attribution 4.0 licence, set on the Tanzil text. Worked out by rule and not reviewed.
