Around 30 pages: the start of the translator's introduction, the passage on abjad numerical values, and a single magic square shown step by step from the rules for making it to the completed illustration.
We would rather you read a portion and decide it is not what you want than purchase 1,465 pages based only on a product description. The extract is supplied as a PDF and uses the actual page design, not a draft version.

What the extract covers
The opening of the introduction. The identity of al-Būnī, the question of the different recensions, and the approach adopted by this edition.
The numerical values of the letters. The complete abjad table as printed in the volume, together with al-Būnī's own remarks on the first nine letters.
A single square, fully demonstrated. One wafq followed from the construction instructions through to the final image, so you can assess the standard of the reproduction before committing to a purchase.
