# Quranic Dataset by Tanzil Project (Qari: Al Afasy)

## Overview
The **Tanzil Project** is an international initiative aimed at providing a highly accurate and verified Quranic text in Unicode. The Tanzil text is refined through rigorous verification processes to ensure adherence to the **Medina Mushaf** and to achieve exceptional precision.

## Text Verification Process
To achieve a high level of accuracy, the Tanzil Project has implemented a three-phase verification process:

1. **Automatic Text Extraction**  
   Multiple authentic Quranic texts were collected, converted into a canonical format, and carefully compared to create a core Quran text.

2. **Rule-Based Verification**  
   A verification program applies grammatical and recitation rules to validate the core text. This program also generates texts in both **Imlaei** and **Uthmani** formats.

3. **Manual Verification**  
   The final text is examined in detail against the **Medina Mushaf**. Each letter and diacritic is checksum-verified to maintain accuracy.
