Hadith of the two weighty things in Islam as mutawatir and the authenticity of it is confirmed by numerous chains of transmission of Shia and Sunni Muslim . According to Ayatollah Ja'far Sobhani, the hadith points the authoritative knowledge of the Ahl al-Bayt and the Quran and convinces Muslim to believe in both of them together. In spite of difference over historical interpretation, Hadith al-Thaqalayn can improve the union among the Muslims world. According to Sunni tradition (canonical Hadith compiler Muslim b. al-Hajjaj), Hadith al-Thaqalayn was presented by Muhammad prophet at a grove called Khumm. In this tradition Yazid b.Hayyan , Husayn b.Sabrah and Umar b.Muslim
Criticism of Hadith to be obsessed with isr’iliyyat, i.e. tales from Jewish lore about earlier prophets. According to author Israr Ahmed Khan, traditional methods used to establish authenticity of hadith rely almost entirely on the personal characters of the reported narrators, and fail to pay enough attention to the actual content of the hadith being evaluated. Among the problems he sees in the traditional hadith analysis are: the inability of some narrators to maintain preciseness of the report, textual conflicts among reports, ignoring textual analysis when the hadith was reported by a narrator of good character, and probability of fabrication of hadith.
