Al-Qalam 68:42

Yawma yukshafu AAan saqin wayudAAawnaila assujoodi fala yastateeAAoon

The Day the shin will be uncovered and they are invited to prostration but they [i.e., the disbelievers] will not be able,

On the Day when the Shin will be exposed, and they will be called upon to prostrate themselves, they will not be able to.
