«الوقتية: وهي الوقتية المطلقة إذا قيدت باللادوام بحسب الذات»
The special temporal proposition is the time-specific simple modality qualified by non-permanence in itself.
The simple time-specific modality asserts a necessary relation at an appointed time. The compound form adds that the relation is not permanent throughout the subject's existence.
Keep two durations separate:
Appointed time: the period in which the qualified relation is necessary.
Subject's full duration: the span over which permanence is denied.
Without this distinction, necessity at a particular time may be incorrectly generalized to necessity at all times.
