The Thesaurus Islamicus Foundation is a non-profit academic organisation that was founded to support and advance the protection, preservation and study of Islamic intellectual and artistic heritage. It specialises in scholarly publishing, fine book design, and the care and management of manuscript collections.
The Foundation has offices in Cairo, Egypt; the University of Cambridge, England; and Stuttgart, Germany.
The Sunna Project is the Foundation’s flagship project. It seeks to assemble the entirety of hadith literature — that is, the literature comprising narrations of the sayings and actions of the Prophet Muhammad . In the Foundation’s Cairo offices, a select group of scholars of Hadith are engaged in preparing definitive critical editions of Hadith collections. This has involved the identification, study and careful comparison of manuscripts from libraries and museums around the world.
The Sunna Project has produced the eighteen volume Hadith Encyclopaedia, which includes the six canonical hadith collections; Sahih al-Bukhari, Sahih Muslim, Sunan Abu Dawud, and the Jami al-Tirmidhi, Sunan Nisa’i,and Sunan Ibn Maja, as well as the Muwatta of Imam Malik ibn Anas. A labour of nearly 100 scholars from around the Muslim world that spanned from 1985 to 2001.
The Foundation has recently in 2008 published the second installment of the Hadith Encyclopedia, which consists of a new fourteen volume edition of the Musnad of Imam Ahmad ibn Hanbal. This edition contains over 120 Hadith from one particular location in the collection that have not appeared in any previous printed edition of the Musnad (in recent times – i.e past ~ 100 years), but which are present in the earlier and more reliable manuscripts. The Project is affiliated with the Prince Alwaleed Bin Talal Centre of Islamic Studies, University of Cambridge.
The ENCYCLOPAEDIA OF HADITH including the Musnad of Imam Ahmed ibn Hanbal can be purchased from tradigital.de . This collection is of a high quality print evident in the Catalog which is worth looking at. It also contains other high quality print works such as the SPLENDOURS OF QUR’AN CALLIGRAPHY & ILLUMINATION, The SERMONS HADITH COLLECTION of the Prophet (pbuh), SHAMA’IL AN-NABI and HAJJ AND ‘UMRA HADITH COLLECTION.
