لأن سخاء غير موجود لا يوصف بالعدوى
For the generosity of someone nonexistent cannot be described as spreading contagiously.
The objection asks how generosity can spread from the patron before he exists. To make “his generosity infected time” intelligible, the bearer of the virtue and its supposed effect must be placed in a coherent relation.
The point is not merely lexical. Even a striking rhetorical fiction requires intelligible connections among the elements of its imagined scene.
