Yawma tashaqqaqul ardu 'anhum siraa'aa; zaalika hashrun 'alainaa yaseer
On the Day the earth breaks away from them [and they emerge] rapidly; that is a gathering easy for Us.
1 Mufti Taqi Usmani
on the Day when the earth will burst apart exposing them, while they will be hurrying up (to come out). That is an assembly, so easy for Us (to muster).
