The votes of Shia and Sunni Scientists about of Ahl al-Bayt (AS) in Hadith of Thaqalayn

One of very important issues in the field of understanding and knowledge in any school is those who explain their school for other people dont provide the field of their confusion for followers of school by the non-scientific interference. Now, this question is about Islam that wheather as the Holy Quran has given the explanation of religion to prophet (PBUH), he also has give explaining of religion to someone or Some people for after himself which to recourse to it is not illegal for Muslims and therefore, if irresponsible and illegal person pay attention to explaining of the religion, is not valid or he doesnt so. Also if he has determined some people to do this, who are they?! In short, who responsible of religion is after the Prophet (PBUH)? In response, Many Hadiths has remained of Prophet Muhammad (PBUH) for this purpose, especially Hadith of Thaqalayn which emphasizes on integral relationship of Ahl al-Bayt (AS) and progeny of the Quran, recourse of people to them and Guarantee about not misleading if people resort to Quran and Ahl al-Bayt (AS). This hadith has imported in Shia and Sunni sources with multiple interpretations, but because of the difference in meaning of Ahl al-Bayt between the Muslim scholars, in practice, mission of this hadith has remained unfinished. This article provides a comprehensive and reasoned theory in this case for readers by a comparative study of the sayings of scholars and Islamic narrators (Sunnis and Shia)about document and content (especially content) of Hadith of Thaqalayn. All Shia scholars and the vast majority of commentators, scholars and Sunni narrators believe that the order of the Ahl al-Bayt (AS) in the purification verse and hadith of Thaqalayn, People who are innocent like Quran, God has removed any impurities of them and they are always with the Quran. They are Ali (AS), Hazrat Zahra (AS) and Hasnain (AS) and the nation should refer and resort only to them, otherwise, they will be misled according to prophet.
