It is narrated from Sayyiduna Salman al-Farisi (may Allah be pleased with him) that he said: Hell (its fire) is black; neither its flames nor its embers give light. Then he recited this verse: "Every time they want to get out of it, from anguish, they will be returned to it" [Surah al-Hajj: 22] . The chain of narration of this hadith is sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) concerning this statement of Allah Almighty: "And whoever intends therein deviation by wrongdoing, We will make him taste a painful punishment" [Surah al-Hajj: 25] , that he said: If a person intends a sin, it is not written against him as long as he has not committed it. But if a person intends to kill someone near the House of Allah while he is in Aden Abyan (a distant place in Yemen), even then Allah will make him taste a painful punishment.

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said concerning this statement of Allah Almighty: "And whoever intends therein deviation by wrongdoing, We will make him taste a painful punishment" [Surah al-Hajj: 25] : "If a person intends deviation (sin) in it (the Sanctuary) while he is in Aden Abyan, Allah Almighty will surely make him taste a painful punishment." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he came to Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with him) and said: O Ibn al-Zubayr, beware of deviation and violation of sanctity in the Sanctuary of Allah, for I heard the Messenger of Allah (peace and blessings be upon him) say: "A man from Quraysh will commit ilhad (violation of sanctity) in it (the Sanctuary). If his sins were weighed against the sins of all jinn and mankind, his scale would outweigh them." The chain of narration of this hadith is sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it.
