وَلَا نُنْزِلُ أَحَدًا مِنْهُمْ جَنَّةً وَلَا نَارًا
We do not definitively assign any particular person among them to Paradise or Hell.
A person’s apparent behavior or reputation does not give certain knowledge of the final outcome. Nor does seeing a sin justify an automatic declaration of eternal damnation. Final reward and punishment belong to Allah’s knowledge and judgment. General promises and warnings remain true, but should not be turned into unsupported individual verdicts.
