SAhi Bukhari Volume 8 Book 76, Number 585

"Abu Huraira narrated that the Prophet said, "On the Day of Resurrection a group of companions will come to me, but will be driven away from the Lake-Fount, and I will say, 'O Lord (those are) my companions!' It will be said, 'You have no knowledge as to what they innovated after you left; they turned apostate as renegades (reverted from Islam)."

This proves that even ashaab can be wrong does it not?
