The common method of the hadith-based exegesis is to collect the traditions which directly deal with a verse or a chapter. Although, it has been a common method, however, it has not been general or permanent. A more complete method is to go beyond the sphere of exegetical traditions and obtain other related traditions, although they are not mentioned in hadith-based exegesis books. In other words, common books of this method are not comprehensive and therefore they are not thoroughly authoritative.
