فَكَانَ عَـٰقِبَتَهُمَآ أَنَّهُمَا فِى ٱلنَّارِ خَـٰلِدَيْنِ فِيهَا ۚ وَذَٰلِكَ جَزَٰٓؤُا۟ ٱلظَّـٰلِمِينَ
“So they will both end up in the Fire, staying there forever. That is the reward of the wrongdoers.”
This ayah is part of Surah al-Hashr, which -- as this event's own significance note states -- was revealed about the expulsion of Banu Nadir (Ibn Abbas RA preferred to call it Surat Banu Nadir).
