The surah introduces a major internal contradiction regarding human free will, claiming that humans are explicitly equipped to choose their own spiritual path, which directly violates orthodox Islamic predestination.
Surah 90:8-10:
Have We not made for him two eyes? And a tongue and two lips? And shown him the two ways?" (In Arabic: Wa-hadaynahu al-najdayn)
Verses 8–10 argue that God has physically equipped humans with senses and intellectual clarity, explicitly guiding them to a clear crossroad (al-najdayn—the two distinct paths of righteousness or wickedness) so they can choose their own destiny.
However, this framework of independent moral agency completely clashes with the absolute determinism found in other parts of the Quran (such as Surah 76:30, which states humans cannot choose unless God forces that choice) and the authoritative Hadith (Sahih al-Bukhari 6596), which states a person’s ultimate destination in heaven or hell was locked in before their birth.
The text cannot logically maintain that humans are standing at a genuine moral crossroad when their footsteps were already completely hardcoded by a divine decree.
