It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said regarding this saying of Allah Almighty: "And he will be given to drink of festering water, which he will try to gulp down" [Surah Ibrahim: 16-17] : "It will be brought near to him and he will loathe it. Then when it is brought closer to him, it will roast his face and the skin of his scalp will fall off. Then when he drinks it, it will cut his intestines until they come out from his rear." Allah Almighty says: "And they will be given boiling water to drink, which will cut their intestines" [Surah Muhammad: 15] . And Allah Almighty says: "And if they cry for relief, they will be relieved with water like molten copper which roasts the faces; how wretched a drink!" [Surah al-Kahf: 29] This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
