“Dispute
you not with the People of the Book (Jews and Christians) except with means better (than mere disputation), unless it be
with those of them
who inflict wrong (and injury): But say: ‘We believe in the Revelation
which has come down
to us and in that which came down to you; our God and your God is One; and it is to Him we bow (in Islam).”
