My Lord has promised me concerning my Ahl al-Bayt that He will not punish them

It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "By the One in whose Hand is my soul! No one will hate us, the Ahl al-Bayt, except that Allah will admit him into the Fire."
This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "My Lord has promised me concerning my Ahl al-Bayt that whoever of them affirms Tawhid (the Oneness of Allah) and affirms my conveying (of the message), He will not punish them." Umar bin Sa'id al-Abahh says: Sa'id bin Abi Arubah died on a Thursday. He had narrated this hadith on a Friday in the mosque, and he died seven days after that. Some people said: "May Allah not reward you with good; (he is) a man of Rafd (Rafidism) and trouble." And some people said: "May Allah reward you with good; (he is) a man of the Sunnah and the Jama'ah; you have conveyed what you heard."
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 Sa'd bin Abi Waqqas (may Allah be pleased with him) that when this verse was revealed: "Let us call our sons and your sons, our women and your women, ourselves and yourselves" [Surah Al Imran: 61], the Messenger of Allah (peace and blessings be upon him) summoned Sayyiduna Ali, Sayyidah Fatimah, Sayyiduna Hasan and Sayyiduna Husayn (may Allah be pleased with them) and supplicated: 'Allahumma ha'ula'i ahli' (O Allah, these are my household).
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 Hanash al-Kinani that he said: I heard Sayyiduna Abu Dharr (may Allah be pleased with him), while holding on to the door of the Ka'bah, say: "Whoever knows me, knows me; and whoever does not know me, then (let him know that) I am Abu Dharr. I heard the Prophet (peace and blessings be upon him) say: 'Behold! The likeness of my household among you is like the ark of Nuh (peace be upon him): whoever boards it is saved, and whoever stays behind from it perishes.'"
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 Sa'd bin Abi Waqqas (may Allah be pleased with him) that when this verse was revealed: "Let us call our sons and your sons" [Surah Al Imran: 61], the Messenger of Allah (peace and blessings be upon him) called Sayyiduna Ali, Sayyidah Fatimah, Sayyiduna Hasan and Sayyiduna Husayn (may Allah be pleased with them) and said: 'Allahumma ha'ula'i ahlu bayti' (O Allah, these are my household).
The two Shaykhs agreed on the soundness of this chain and used it as evidence, but they did not record it in this place; with this same chain they recorded only the story of Abu Turab.
