فلك يريد به هلالاً طلعاً متزيداً ويعود في نقصان ويريد جرما النيرون كليهما يتقابلان به ويجتمعان ويريد مبلغ سير كل منهما في العام أو في الشهر أو في اﻵن نتجته همة عالم بصنائع بنيت على التحقيق والبرهان انظر ٳلى فلك يريد عجابياً فيه تبين حكمة الرحمن حركاته شتى بفرد محرك وله معاني فوق كل معاني في سنة خيع (؟) هجرية | ‘Star’ [or 'Heavenly Body'] means an ascending and increasing crescent which decreases again. ‘Sun’ and ‘Moon’ means that both of them face each other and meet. The duration [extent?] of the way of each of them in the year, or in the month or a particular time is a result of the design of him who knows the sciences which are based on methods of verification and demonstrative proof. ‘Look at the heavenly bodies’ means something wonderful in which the wisdom of the Merciful appears through different motions with a single mover. He has different meanings above all meanings. In the year 618 A.H. | Around the entire rim | General explanation |
