بAbjad & Magic Squares

The Arabic science of letters as a working table, with a 3×3 wafq to lay yourself, number by number, until every line comes to its sum: count any word letter by letter in the abjad, in the eastern or the older western reckoning, from an on-screen keyboard in the old order; write any number in abjad letters, and read a sum as a Hijri year; build the 3×3 and 4×4 magic squares (wafq) for a word's value or any number, every line checked, in numbers or in letters, to save as a picture; see the buduḥ square with its corner letters; and lay four letters of a name in a Latin square, as al-Būnī did. All ninety-nine Beautiful Names are listed with their numbers, to search, sort and count, and any word shows the names that share its number; the disconnected letters that open twenty-nine suras are tabled with their values; and the abjad is set beside the Hebrew alphabet it shares its order with. Learn the order by tapping the letters into it against the clock, word by word of the rhyme, and the numbers by a quiz that keeps asking what you miss; make a chronogram, a phrase whose letters add up to a chosen year, with the count of what is still to find and the names that would make it up, after the famous one for the conquest of Constantinople; and lay the 4×4 square by hand as well as the 3×3.
