Accuracy matters, especially with the Quran. Here is exactly where the content on Flash Quran comes from.
Arabic text
The Arabic is the Uthmani script in the narration of Hafs from 'Asim, the most widely used reading in the world, sourced through the Tanzil project and the alquran.cloud API.
Translations
Translations are the work of established translators, sourced through the alquran.cloud and Tanzil projects. They include Saheeh International (English), the Indonesian Ministry of Religious Affairs, Fateh Muhammad Jalandhry (Urdu), the Turkish Directorate of Religious Affairs (Diyanet), Mohammad Mahdi Fooladvand (Persian), Muhammad Hamidullah (French), Elmir Kuliev (Russian), Abdullah Muhammad Basmeih (Malay), Abubakar Mahmoud Gumi (Hausa), Ali Muhsin Al-Barwani (Swahili), Muhammad Sodik Muhammad Yusuf (Uzbek), Besim Korkut (Bosnian), Muhammad Ma Jian (Chinese), and others for Bengali, Hindi, Tamil, Pashto, Azerbaijani, and Somali.
Transliteration
The Latin transliteration is sourced through the alquran.cloud API. It is a guide to pronunciation and is not a substitute for learning to read the Arabic script.
Audio recitation
The recitation is by Sheikh Mishary Rashid Alafasy, served through the islamic.network audio CDN.
Surah overviews and virtues
The overview for each surah is an editorial summary written to introduce its themes. The virtues (fada'il) are included only where they come from authentic narrations, and each one is cited to its source, such as Sahih al-Bukhari, Sahih Muslim, or Sunan at-Tirmidhi. Where a commonly circulated benefit does not have an authentic basis, it is left out on purpose.
