In these verses the Qur'an has framed a conditional proposition, which
exempts or excludes the antecedent premise for arriving at a conclusion
which is consequent upon it. Thus the Qur'an aims at emphasizing the role
of reason and refutes the view of some of the religions that faith is alien
to, or, is incompatible with reason, and that to embrace faith one has
to suspend his rational faculty and concentrate upon heart alone, so that
it may absorb the Divine light and become illuminated by it. This view
is totally negated and refuted by the Qur'an.
