Begins (f. 86v, pp. 2-7):
Praise be to Allah, the Almighty, Who unites with glory and the ancient remnant, who separates in perfection

The wise who walks with his wisdom around the green dome the wise who does not Arabize
About the knowledge of the equal of a grain of sand in the earth and not in the heavens and prayer on the Prophet Muhammad Khatam
The prophets and their family and companions of piety and peace bowed down a lot and then I mentioned it
Who can be among the people of wisdom
Ends (f. 103v, lines 15-20):
... Then make this line by the center of the pole and then open the volcanoes
From the end of the equator by the value of each of the countries in the table
The multiple dimensions of the slaves and the position of the man at the center and the man
Lastly, in the struggle of Mammask, I searched every point, point by point, and offered a book
Your city is looking for your point on the other side of the equator and so on
