عنوان مقاله [English]
Ulama’ and Imamiyyah scholar of Hadith, especially until the 7th century before the Seyyed Ibn Tavus and the late Allameh, have paid more attention to reliable (MOVATHAGH) Hadith than to the (THEGHE) Hadith of trust, and trusting the issuance from the source of the innocent (MA’ASUM) has been more important than trusting transferor, and therefore, the scholars of the Imamiyyah, especially their predecessors, unlike the Sunni scholars, who from the very beginning had categorized the hadiths according to the status of the narrator according to their opinion, have arranged the hadiths in their books in this way, unlike the general public. Therefore, the weakness or unknownness of some narrators, or discontinued in the Isnad, or such problems, did not make their Hadiths invalid, and they mentioned them in their Haditg books. In the meantime, a group of scholars have tried to correct the hadiths that have such weaknesses and problems with methods. One of these methods is the Isnad replacement method, which is discussed in this article.
