Hadith is a free Android app developed by Qatar Charity that offers the most comprehensive encyclopedia of Hadith. The app provides offline access to the nine books of Hadith, including Sahih Muslim, Sahih Al-Bukhari, Sunan Al-Nisa’i, Sunan Al-Tirmidhi, Sunan Ibn Majah, Sunan Abi Dawood, Muwatta Malik, Musnad Ahmad, and Sunan Al-Darimi.

The app features an indexing system that displays the original book indexes in two levels, making it easy to access the Hadiths. Each Hadith is numbered as mentioned in the original books and attributed to their sources, number, and original and subtopic subject title. The app also allows you to change the font size of each Hadith, and you can easily navigate within one book's Hadiths. Additionally, you can search all nine books using a single word or a set of words, and it is also possible to search with matching or similar words. Finally, you can share the Hadith as a picture to ensure the quality of the presentation and integrity of the text.
