مِنَ الْجِنَّةِ وَالنَّاسِ
From among jinn and humankind. (114:6)
Classical syntax allows different attachments for this last phrase, including clarification of the whispering agent and alternative readings through apposition or another connection to earlier words. A widely understood sense includes whisperers from both jinn and humans; it does not say every human is a whisperer.
Al-nās is coordinated with al-jinnah within the phrase. Its wider attachment should be explained as an area of grammatical interpretation, not as a universally settled single parse.
