That Day, they [i.e., everyone] will follow [the call of] the Caller1 [with] no deviation therefrom, and [all] voices will be stilled before the Most Merciful, so you will not hear except a whisper [of footsteps].
On that day, people will follow the sound of the caller towards the gathering place. There will be nothing to divert them from following it. The voices will silence for the Merciful, out of fear, so you will not hear on this day except whispering.
