O people of the city! Ye have disbelieved your Lord. If
ye are truly faithful to Muhammad, the Apostle of God
and the Seal of the Prophets, and if ye follow His Book,
the Qur’án, which is free from error, then here is the like
of it—this Book, which We have, in truth and by the leave
of God, sent down unto Our Servant. If ye fail to believe
in Him, then your faith in Muhammad and His Book which
was revealed in the past will indeed be treated as false in the
estimation of God. If ye deny Him, the fact of your having
denied Muhammad and His Book will, in very truth and
with absolute certainty, become evident unto yourselves.
Chapter IV.
