Abu Umama reported,

The Prophet ﷺ said regarding Allah's words "and he will be given pus to drink, gulping it down", "It will be brought near him and he will recoil from it. When it draws close, it will scorch his face and the skin of his scalp will fall off. When he drinks it, it will tear his intestines apart until it comes out from his rear."Allah says, "and they will be given boiling water to drink that tears apart their intestines" [Muhammad 47:15].And Allah says, "And if they cry for relief, they will be relieved with water like molten metal that scorches the faces. What a wretched drink" [Kahf 18:29].

عن أبي أمامة

عن النبي ﷺ في قوله {ويسقى من ماء صديد يتجرعه} قال يقرب إليه فيتكرهه فإذا دنا منه شوي وجهه ووقعت فروة رأسه وإذا شربه قطع أمعاءه حتى خرج من دبره يقول الله عز وجل {وسقوا ماء حميما فقطع أمعاءهم} ويقول الله {وإن يستغيثوا يغاثوا بماء كالمهل يشوي الوجوه بئس الشراب}
