فِي أَحْسَنِ تَقْوِيمٍ
In the best constitution. (95:4)
Aḥsani is an elative form in an iḍāfah construction with taqwīm; the whole phrase follows fī. The wording draws attention to the excellence and order of human creation, not simply a momentary personal condition.
Explanatory discussions may stress physical form, intellectual capacities or the human moral vocation. Which aspect receives emphasis depends on the broader context and interpretation; the wording should not be compressed into one exclusive secondary application.
