A demonstrative pronoun is a noun (اسم) which is used to point to something that has already been mentioned in some form or another. The pointing is either near (“this”), medial, or distant (“that”). For example:
هذا كتاب مبين
This is a clear book
كلما رُزقوا منها ... قالوا هذا الذي رُزقنا من قبل
Whenever they are to be given sustenance therein,
they shall say, “this (i.e. this sustenance) is what we have been given prior.”
The demonstrative pronoun itself is definite.
