Your gaze is a borrowed, fleeting hand, and your fault is the sin of the towering palm.

This profound couplet explores the delicate balance between human frailty and divine judgment. The poet suggests that while the act of turning away (or the 'stolen glance') might seem small, the transgression itself is monumental. It is not just a minor mistake; it is a sin against the towering, perfect structure—the 'Nakhil-e-Buland' (the lofty palm). Allama Iqbal reminds us that even the smallest deviation from the path of righteousness carries immense weight.
