| Sample Text | fol.1b.1: In the name of God, the Most Gracious, the Most Merciful fol.1b.3: Praise be to God, the Creator of the morning and who gives rest to the night, and the sun and the moon are our reckoning. fol.2a.2: Then, here is a brief introduction to extracting the workings of the night and day from the quarter of the circle called the Mujib Quarter. I made it a means for the beginner in the science of timing to use its reading to arrive at other lengthy chapters. I shortened it from the letters of the scholar Sheikh Abu Abdullah al-Mardini and others and arranged it into an introduction, seventeen fifteen chapters and a conclusion - fol.28a.6: If one of them is cut from the beginning of the arc of elevation just as the other is cut from its end, then it is correct. You place the string on the prongs and know by sight what number you want, then transfer the string to the cosine. If the mirror cuts such a number, it is correct, and God knows best. |
