The Hadits of the 70 Sects Has Inauthentic Chains

بِسۡمِ ٱللهِ ٱلرَّحۡمَـٰنِ ٱلرَّحِيمِ

Imam Abu Muhammad ʿAli ibn Ahmad ibn Hazm (r.a.) mentioned two ahadits used as proof by those who accuse others of disbelief and which they falsely attribute to the Messenger of Allah (s.a.w.).  These are, “The Qadariyyah and Murji’ah are the magus of this ummah;” and, “This ummah will divide into 70 or 70 something groups; all of them will be in Hellfire except one, which will be in Jannah.”  In his commentary on the two previously mentioned ahadits, Imam ibn Hazm (r.a.) said, “In the first place, their chains of transmission are unauthentic.  Any ahadits with an unauthentic ascription cannot be used as proof according to the opinion of the ahadits scholars who recognise the hadits with khabar al-wahid.  So, what then of those who do not recognise it?”
