of excerpt on magic squares (f. 131r, lines 16-17):

Ends (f. 132v, lines 8-11):

If there are ten for a mother, they inherit a third, so each five gets a sixth, and five of these ten are annuities and the remaining five.
With Nawa'im also, they may narrate two-thirds, so the five cousins who are maternal brothers become one-third, along with the previous sixth, so half becomes with them.
Together with the five cousins who are not maternal brothers, they inherit one-third, and the five maternal brothers only inherit one-sixth, and God knows best
