161. " verily those who reject faith, and die while they are infidels,
upon them shall be the curse of allah, (of) the angels,
and (of) mankind all together."
162. " abiding therein forever, the torment shall not be lightened for them
nor shall they be given respite."
163. " and your god is one god. there is no god but he;
he is the beneficent, the merciful."

commentary:

it was described in the former verses that if the people who
conceal the fact repent and express the reality, they will be involved in
the mercy and grace of allah. but in this verse they are warned that if
they do not repent and remain in the state of infidelity until they die,
they will be in the same situation that allah, angels and all people
curse them. of course, the repentance that occurs before death is
accepted, but the repentance at the moment of death is not helpful.

at first, it says:

" verily those who reject faith, and die while they are infidels,
upon them shall be the curse of allah, (of) the angels,
and (of) mankind all together."

this group of infidels, similar to the aforementioned group, are
involved in the curse of allah, angels, and people, too. the difference
is that this group, because of their continuous insistence on being
faithless, can not have a way to return to the right path.

then, it adds:

" abiding therein forever, the torment shall not be lightened for them
nor shall they be given respite."

since the principle of the faith in theism can put an end to all
these misfortunes, in the last verse of this group of verses, it says:

" and your god is one god. ..."

again, to emphasize more, it says:

"... there is no god but he;..."

then, at the end of the verse, as the reason for that statement, it
adds:"...he is the beneficent, the merciful."

yes, only the one, whose general mercy encompasses all
creatures, on one side, and on the other side, whose specific mercy
reaches the true believers, deserves servitude, and no one else.
