[4.171] People of the Book, do not exaggerate
your religion. Do not say about Allah except
the truth. Indeed, the Messiah, Jesus son of
Mary, is only a Messenger (and Prophet) of
Allah, and His Word (Be) which He gave to
Mary, and a (created) spirit by Him. So believe
in Allah and His Messengers and do not say:
'Trinity.' Refrain, it is better for you. Allah is
only One God. Exaltations to Him that He
should have son! To Him belongs all that is in
the heavens and in the earth, it is sufficient
that Allah is the Guardian.
