Through the Sunna Project the Foundation seeks to assemble the entirety of hadith litertaure and to prepare and publish definitive critical editions of every hadith collection. The Foundation engages nearly one hundred scholars of hadith in the study and comparison of manuscript and printed copies of hadith collections from libraries and museums around the world. The Sunna Project is affiliated with the Prince Alwaleed Bin Talal Centre of Islamic Studies, University of Cambridge.
