الطبيعيات: علم يتعلق بأمور يتوقف على مادة في التصور والوجود الذهني والخارجي
Natural philosophy concerns matters dependent upon matter in conception and in mental and external existence.
Ṭabīʿiyyāt (natural philosophy) studies things for which matter is integral to their nature and actual existence. Bodies, motion, change, and physical qualities are representative subjects. This classification belongs to the language of classical philosophical sciences, not to a complete taxonomy of modern academic departments.
Example: To describe an actual wooden plank as a physical object, we cannot detach it from its extension and material constitution.
Such questions become relevant to kalām when theologians examine arguments about bodies, temporal origination, motion, or the composition of physical objects.
