Sayyid Murtadha al-Askari, the renowned scholar, has very ably made a probe into the History of the delicate institution of Hadith and very ably unveiled the picture of the institution of Hadith in such a superb manner that every line and contour of its countenance becomes distinctly clear. His scholarly and unbiased analysis of the subject invites the attention of the Muslims all over the world to view the subject dispassionately and try to differentiate and dissociate the authentic from the unauthentic and fabricated Hadith. In this way it will be a great service to Islam to introduce it in its true colours and contours through the help of reliable and authentic Hadith.
