Since the inception of the ancient era, it has been the utmost trial of scholars related to every field of knowledge that they could save the knowledge of various fields. For meeting the purpose of saving, different tasks had been done in different periods, but, the most appreciating one is the preparation of an encyclopedia. In every era, different encyclopedias of different arts have been designed. Although the processes in Islamic studies remained to continue and various encyclopedias in the Islamic studies were prepared in which the encyclopedia of hadith is the most popular. Therefore, the compilation of hadith has begun from the 3rd Islamic century and a large number of muhadiseen have rendered their best services in this field and represented Hadith and books related to all arts, but, along with that a very important task was to assemble all books of Hadith at one place so that no one may get in trouble to find the Hadith, but it was a hard nut to crack that is why Allah has chosen such scholars who have compiled all the Hadith with their untiring efforts out of them the topmost in the list are: Jama-al-Joma, Kanzal-al-Amal, Almusand-al-Jamia, Mosoaa, Jamiat-ul-ahadees-al-zaeefa wal-mozooat, and almudavina-tul-Jamia are included.
