Be a scholar or a learner, or a person who loves [the scholars] or a follower [of the scholars], but do not be the fifth.
Humayd (one of the reporters) asked Al-Hasan (Al-Basri, who reported this from Abû Al-Dardâ`), “And who is the fifth?” He replied, “A heretic (mubtadi’, religious innovator).”
~ Abu Ad-Darda (RA)
