وَفِي اللَّحْدِ مَقِيلُكَ فَمَا قِيلُكَ؟
And in the grave lies your resting place; what will you have to say?
Laḥd is the side-niche in a grave, here evoking burial. Maqīl is a place of repose or staying, while qīl is connected with speech or what is said.
The near echo maqīluka / qīluka carries the listener from an image of the place of burial to the issue of accountability for what one can say.
