quran:104:1 – In the name of Allah, the Entirely Merciful, the Especially Merciful.

Woe to every scorner and mocker  

Woe (waylun: an expression implying chastisement) to every backbiter, ˹who is a˺ slanderer, frequently engaging in backbiting and slander, that is to say, defamation — this was revealed regarding those who slandered the Prophet (s) and the believers, the likes of Umayya b. Khalaf, al-Walīd b. al-Mughīra and others —
القرآن:١٠٤:١ – بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ

وَيْلٌ لِكُلِّ هُمَزَةٍ لُمَزَةٍ  

{ويل} كلمة عذاب أو وادٍ في جهنم {لكل هُمزة لُمزة} أي كثير الهمز واللمز، أي الغيبة نزلت فيمن كان يغتاب النبي ﷺ والمؤمنين كأُمية بن خلف والوليد بن المغيرة وغيرهما.
