Reason v. Revelation (or: 'aql wa naql)

"It is possible for reason to conflict with the revelation,
so we must prefer one over the other" is a false premise.

In reality, we know that revelation is true
because of our faculties (including our reasoning);
indeed, revelation commands the utilisation of reason.
There can be no contradiction between the two.

As an ideal of revelation, certainty of faith
does not arise as an expression of the whole individual
except with voluntary submission, and the necessity
of its reasoning & intellect in the attaining of knowledge.

Belief is an individual's affirmation of an existence
which is either true or false, and corroborated through some justification.
Credulity is believing without evidence,
and Delusion is affirmation in light of overwhelming evidence to the contrary,
while Knowledge is a true, justified & certain belief that matches reality.
If one is certain in a belief,
and this belief is true in reality,
then this belief is knowledge.
