أَيَطْمَعُ كُلُّ ٱمْرِئٍ مِّنْهُمْ أَن يُدْخَلَ جَنَّةَ نَعِيمٍ
Ayatma'u kullum ri'im minhum anyyudkhala jannata Na'eem
Onlardan herbiri nimet bahçesine konulacağını mı umuyor?
Does each one of them hope to be admitted into a garden of bliss?
The construction is distributive, each single man of them, so the assumption being described is held privately, one person at a time. Tama' is greedy hoping rather than expectation resting on anything. The answer the passage gives is their origin, which is everyone's origin, and that removes the ground on which a person quietly assumes he is the exception.
