No book of hadith sciences is devoid of the subject of sahih hadith whether small or big, old or contemporary. But there is not any comprehensive book that deals with all the details of sahih hadith, encompasses all its important topics and removes all the objections raised about it.

Praise be to God Almighty, Shaykh-ul-Islam Dr Muhammad Tahir-ul-Qadri filled this gap in the books of hadith studies, and wrote a comprehensive and all-encompassing book on this subject including all its aspects. This book is a part of his Encyclopedia of Hadith Studies.
