如今这个时代，已无法真正体会圣训学者（muḥaddithīn）为保存圣训所付出的巨大牺牲，以及他们为克服种种困难与障碍而奋斗的艰辛。正是这些牺牲，使得今天的每一个词，乃至每一个字母，都得到了完整的保存。圣训学者为保存圣训所确立的规则，使这门学科成为独立的学问；要深入圣训知识与圣训学原理（ʿUlūm al-Ḥadīth），必须学习这些规则。 这本小册子旨在向读者介绍圣训知识。书中探讨了一些重要问题，如圣训是如何编纂的、圣训的保存、判断圣训真伪与强弱的原则、圣训的重要性，以及各类圣训典籍。书末附有若干著名圣训学者的简短传记。此书可视为掌握这门学问所需见识的第一步。若读者读后对圣训重新产生了亲近之感，愿这能成为作者得救的途径。恳请读者为作者、其父母及家人祈祷，愿真主在今世和后世赐福他们。

It is not possible in this day and age to comprehend the great sacrifices that were made by the hadith masters [muúaddithīn] or the difficulties and barriers they struggled to overcome for the preservation of hadith. It is a result of these sacrifices that today each word, in fact each letter of the aúódõth are fully preserved. The rules the hadith masters established to preserve the hadith and by which this branch of knowledge became a distinct science are necessary for one to learn and make headway into both the knowledge of hadith and principles of hadith [uüñl al-úadīth].. This short booklet is written to introduce the reader to the knowledge of hadith. It discusses important issues such as how the hadith were compiled, the preservation of hadith, principles regarding the authenticity and weakness in a hadith, the importance of hadith and the various types of hadith books. It ends with short biographies of some of the famous hadith masters. This booklet may be looked upon as a first step in acquiring the insight that is necessary for advancing in this science. After reading this booklet, if one feels a renewed connection with the hadith, it is hoped that it will be a way of salvation for its author. The readers are requested to pray for the author, his parents and his family and that Allah bless them in this world and the Hereafter.
