Surah Az-Zukhruf 43:65

فَٱخْتَلَفَ ٱلْأَحْزَابُ مِنۢ بَيْنِهِمْ ۖ فَوَيْلٌ لِّلَّذِينَ ظَلَمُوا۟ مِنْ عَذَابِ يَوْمٍ أَلِيمٍ

But the denominations from among them differed [and separated], so woe to those who have wronged from the punishment of a painful Day.

Translation: Saheeh International

Tafsir

But the factions differed among themselves regarding the status of Jesus was he God or the son of God or the third of Three deities? So woe waylun is a term implying chastisement to those who do wrong those who blaspheme in what they say about Jesus from the chastisement of a painful day.
