The benefits of derivation knowledge in validating of hadith (by samples comparison)

During the history, hadith has suffered from reference and textual damages. This factor has led to some people criticized over the traditions and caused less attention for some people. Identifying the increasing criteria for the validity of the traditions is a necessary requirement. Hadith derivation reveals various documents, multiple sources, various contents and similar texts for each tradition. Of course, this article will examine the content further. Comparing and matching the multiple documents and texts with each other, eliminates many of the apparent and basic problems of tradition and improves its validity. The purpose of this research is to explain the role of hadith derivation in increasing the validity of the hadith and its usefulness in addition to identifying the effective criteria in the validity of tradition, fixing of documentary and textual problems for many hadiths. This research, for the first time, by presenting numerous examples, would prove the role of derivation in the validation of tradition in two areas of the document and text.
