Shia and Innovations!
There is an authentic hadith in Al-Kafi, the shia hadith book
H 163, Ch. 19, h 9
Ali ibn Ibrahim has narrated from his father from Muhammad ibn ’Isma‘il from al-Fadl ibn
Shadhan in a marfu‘ manner (rafa'ahu) from abu Ja’far and abu ‘Abdallah (a.s.) who have
said the following.
"All innovations are misguidance and all misguidance leads to Hell."
This is present in both shia and sunni hadith books.
