Among the infidels are those who have repudiated His Self
and risen up against His Cause, and who claim that these divine verses are
contrived. Such also were the objections of the deniers of old, who now implore
deliverance from the Fire. Say: Woe betide you for the idle words that
proceed from your mouths! If these
verses be indeed contrived, then by what proof have ye believed in God? Produce
it, if ye be men of understanding! Whensoever We revealed Our clear verses unto
such men, they rejected them, and whensoever they beheld that which the
combined forces of the earth are powerless to produce, they pronounced it
sorcery.
(Baha'u'llah, Suriy-i-Haykal, The Summons of the Lord of Hosts)
