Musnad Ahmad Hadith 22285

It is narrated from Abu Umamah (may Allah be pleased with him) that the Noble Prophet (ﷺ) explained the Quranic verse "And he will be given to drink of pus" by saying: The inhabitant of Hell will be given the water of pus to drink. When that water is brought near to him, he will feel disgust for it. When it is brought even closer, his face will burn and the hair of his head will fall off.
