فَاتْرُكُوا الطَّيْخَ وَالتَّعَاشِيَ وَإِمَّا تَتَعَاشَوْا فَفِي التَّعَاشِي الدَّاءُ
Meaning: Leave arrogance and the pretence of blindness; if you persist in wilfully refusing to see, the harm lies in that very conduct.
Fa-trukū is a plural imperative. Al-ṭaykh is pride or insolence; al-taʿāshī refers to pretending not to see, or deliberately disregarding what is evident. It is a metaphor for wilful blindness to facts, not a medical claim.
The conditional wa-immā tataʿāshaw warns that persistence in this posture carries its own harm. The argument now shifts from boasting about military action to admonition about conduct and judgment.
