all his books this is most clearly shown and most truly proved in his book
called The Niche for Lights.
THE SECOND DISCUSSION
THE REFUTATION OF THEIR THEORY OF THE
INCORRUPTIBILITY OF THE WORLD AND OF TIME AND
MOTION
Ghazali says:
Know that this is part of the first question, for according to
the philosophers the existence of the world, having no
beginning, does not end either; it is eternal, without a final
term. Its disappearance and its corruption cannot be
imagined; it never began to exist in the condition in which it
exists’ and it will never cease to exist in the condition in
which it exists.
Their four arguments which we have mentioned in our
discussion of its eternity in the past refer also to its eternity in
the future, and the objection is the same without any
difference. They say that the world is caused, and that its
cause is without beginning or end, and that this applies both
to the effect and to the cause, and that, if the cause does not
change, the effect cannot change either; upon this they build
their proof of the impossibility of its beginning, and the same
applies to its ending. This is their first proof.
The second proof is that an eventual annihilation of the
world must occur alter its existence, but ‘after’ implies an
affirmation of time.
