إِنَّ الْإِنْسَانَ لَفِي خُسْرٍ
Humanity is surely in loss. (العصر: 2)
أَلْهَاكُمُ التَّكَاثُرُ
Rivalry for increase distracted you. (التكاثر: 1)
Al-ʿAṣr uses al-insān to state a general human condition and then qualifies it with an exception outlining escape. Al-Takāthur directly confronts its listeners through -kum and ends with accountability. The former is organized around illā; the latter repeatedly uses kallā, futurity and verbal emphasis to warn.
The point is not to rank the passages but to see how audience and communicative objective shape syntax and diction. Similar concern for human life and its outcome can be expressed through distinct patterns of address and rhetorical development.
