It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) concerning the saying of Allah Almighty: "In which they will remain for ages (ahqab)" [Al-Naba': 23] , that he said: One "huqb" is a period of eighty years. This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) concerning the saying of Allah Almighty: "And a cup full (dihaq)" [Al-Naba': 34] , that he said: It refers to a cup of drink that is (drunk) in succession and is filled to the brim. He further said: Many a time I heard (my father) Sayyiduna Abbas (may Allah be pleased with him) say: "Give us to drink and fill our cups to the brim," that is, he would use the word "idhaq". This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Muhammad bin Yazid bin Khunays (may Allah have mercy on him) that he said: We were with Sufyan al-Thawri (may Allah have mercy on him), visiting him in his illness, when Sa'id bin Hassan al-Makhzumi came in to him. He was the preacher of our congregation and used to lead us in prayer in the month of Ramadan. Sufyan al-Thawri asked him: "How does that hadith go which you narrated to me on the authority of Umm Salih?" He replied: Umm Salih narrated to me from Safiyyah bint Shaybah, and she from Sayyidah Umm Habibah (may Allah be pleased with her), that the Messenger of Allah (peace and blessings be upon him) said: "Every word of the son of Adam counts against him, not for him, except enjoining what is right, forbidding what is wrong, or the remembrance of Allah, the Mighty and Majestic." Muhammad bin Yazid said: I said (on hearing this): "This is a very severe warning indeed!" At that Sufyan al-Thawri said: "What is severe about this hadith? It has only been narrated by one woman from another woman, and she from a third woman, whereas this very truth is also present in the Book of Allah, the Mighty and Majestic, with which your Prophet (peace and blessings be upon him) was sent. Allah Almighty says: 'The Day that the Spirit (Jibril, peace be upon him) and the angels will stand in rows, they will not speak except one whom the Most Merciful permits, and he will say what is right' [Al-Naba': 38] . And He said: 'By time, indeed mankind is in loss, except those who believe and do righteous deeds and advise one another to truth and advise one another to patience' [Al-Asr: 1-3] . And He said: 'There is no good in much of their private conversation, except for those who enjoin charity or what is right or reconciliation between people' [Al-Nisa': 114] ."

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) concerning the saying of Allah Almighty "By those who pull out violently, and by those who draw out gently" [Surah al-Nazi'at: 1-2] , that he said: (What is meant by them are the angels of) death. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) that when a quarter of the night had passed, the Messenger of Allah (peace and blessings be upon him) would (wake and) say: "O people, remember Allah! O people, remember Allah! (The first blast of the Trumpet,) al-Rajifah, has come, to be followed by (the second blast,) al-Radifah. Death has come with all its horrors, death has come with all its horrors." So Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) said: O Messenger of Allah, I send abundant blessings upon you; so how much of my supplication should I devote to you (for sending blessings)? He (peace and blessings be upon him) said: "As much as you wish." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) used to be asked about the Hour, until these verses were revealed to him (peace and blessings be upon him): "They ask you about the Hour: when will it be established? What have you to do with mentioning it? Its knowledge rests only with your Lord." [Surah al-Nazi'at: 42-44] So he (peace and blessings be upon him) refrained (from speaking about it). This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it, because Ibn Uyaynah, in the last part of his life, used to narrate it in mursal form.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the surah "He frowned and turned away" was revealed concerning the blind Companion Ibn Umm Maktum (may Allah be pleased with him). He came to the Messenger of Allah (peace and blessings be upon him) and began saying: (O Messenger of Allah,) guide me. At that time some of the great chiefs of the polytheists were sitting with the Messenger of Allah (peace and blessings be upon him), so the Messenger of Allah (peace and blessings be upon him) turned away from him (the blind Companion) and turned towards those chiefs, asking them: "Do you see any harm in what I am saying?" And they would say: No. So on this occasion "He frowned and turned away" [Surah Abasa: 1] was revealed. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it, because a group of narrators has narrated it from Hisham bin Urwah in mursal form.

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that he heard Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) reciting these verses: "Then We caused grain to grow therein, and grapes and fodder, and olives and date palms, and gardens of dense trees, and fruit and abb" [Surah Abasa: 27-31] . Then (Umar al-Faruq (may Allah be pleased with him)) said: All of this we know, but what is meant by "abb"? Then he shook the stick that was in his hand and said: By Allah, this is affectation (delving into the depths of meanings)! Follow what has become clear to you from this Book. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from the Mother of the Believers Sayyidah Sawdah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "People will be raised (on the Day of Resurrection) barefoot, naked and uncircumcised; the sweat will reach their mouths like a bridle and will reach the lobes of their ears." Sayyidah Sawdah (may Allah be pleased with her) said: I said: O Messenger of Allah, how shameful! Will we look at one another? He (peace and blessings be upon him) said: "At that time people will be heedless of that (looking) and preoccupied (with their own concern)." Then the Messenger of Allah (peace and blessings be upon him) recited these verses: "On the Day a man will flee from his brother, and his mother and his father, and his wife and his sons. Every man among them that Day will have a matter enough to occupy him (from others)." [Surah Abasa: 34-37] This hadith is sahih (authentic) on the condition of Imam Muslim, but they did not record it with this wording; rather, the two Shaykhs agreed on recording it in abridged form through the narration of Hatim bin Abi Saghirah from Aishah (may Allah be pleased with her).

It is narrated from Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) concerning the saying of Allah Almighty "And the earth and the mountains are lifted up and crushed with a single crushing" [Surah al-Haqqah: 14] , that he said: The two of them (the earth and the mountains) will be crushed to pieces and fall as dust upon the faces of the disbelievers, not upon the faces of the believers; and this is the saying of Allah Almighty: "And many faces that Day will have dust upon them, darkness covering them." [Surah Abasa: 40-41] This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
