It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever recites Surah al-Kahf on the day of Jumu'ah (Friday), light will be made to shine for him for the period between the two Fridays." The chain of this hadith is sahih (authentic), and the two Shaykhs did not record it.

It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said concerning the 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 (the water) 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 to pieces until they come out of his rear." Allah Almighty says: "And they will be given boiling water to drink, which will cut their intestines to pieces." [Surah Muhammad: 15] And Allah Almighty says: "And if they call for relief, they will be relieved with water like molten copper, which roasts the faces. How wretched the drink!" [Surah al-Kahf: 29] The chain of this hadith is sahih (authentic), and the two Shaykhs did not record it.
