The Meaning of the Jurists' Phrase "After the Shadow of Noon" and How It Is Calculated

Question:
He says: The fact that the shadow becomes equal to the object is a clear matter, but what is the meaning of the jurists' (may Allah have mercy on them) phrase "after the shadow of noon," and how is that calculated?

Answer:
The inclination means that the sun inclines from overhead in winter and in summer. When it inclines, a shadow is cast. When it inclines toward the south at the time of Dhuhr, a small shadow is cast toward the north; this is the shadow of the inclination, called the shadow of noon. When it inclines toward the north in the summer, its shadow at the time of noon is cast toward the south, which is called the shadow of the inclination. This cancels out what is calculated from noon. That is why they say "after the shadow of noon," meaning that the shadow of every object becomes equal to it after the shadow of noon, which means that the shadow of noon is canceled out.
