فَلْيَدْعُ نَادِيَهُ
“Let him call his assembly.”
In Qurʾān 96:17, nādī refers to the meeting place or assembly, while the persons who can respond to a summons are the people associated with it. The place designates its occupants.
Original sense: meeting place.
Intended sense: those gathered there.
Relation: locality or place-for-people.
The action “call” helps direct the listener from the location to the persons meant by the utterance.
