Passage from
the Qur'an ascribed to 'Uthman ibn 'Affan, third Caliph,
(644-656AD)

[... Is it
that whenever there comes to you an Apostle with what ye yourselves desire not,
ye are puffed up with pride?--- some ye called impostors, and others ye slay! They
say, "Our hearts are the wrappings (which preserve God's Word: we need no more)."
Nay, God's curse is on them for their blasphemy: little is it they believe.]
[Qur'an
2:87-88]
