Analysis of Criterion Criteria: A Case Study of Sura Yas

Cognition of surah or the method of structural research in Holy Quran is a branch of Quranic sciences that provides ground for ponder (tadabbor) and study of the Quran in a way that forge a relationship with Quran. According to advice of the Innocents (pbuh) to form relationship with surahs and due to the importance of surah Yasin which explained in several hadiths, a painstaking research has not been done about cognition of this surah. Therefore, status, purposes, thematic axis, and particular features of Surah Yasin has been examined. By examining verses related to monotheism, prophecy, and resurrection in this surah, the cause of calling this surah as “heart” became more evident. In this regard, by examining the relation between surah Yasin and contiguous and similar surahs, the key point of surah recognized as "to find out the direct path and passing this way" which is following Quran and the Prophet's households (pbuh).
