It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said to me and to Abu Bakr (may Allah be pleased with him) on the day of the Battle of Badr: "On the right of one of you is Jibril (peace be upon him), and with the other is Mika'il (peace be upon him), while Israfil (peace be upon him) is a mighty angel who attends the fighting and is present in the ranks." 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 Abu Sa'id al-Khudri (may Allah be pleased with him) that people complained to the Messenger of Allah (peace and blessings be upon him) about Sayyiduna Ali bin Abi Talib (may Allah be pleased with him), so he (peace and blessings be upon him) stood among us to deliver an address, and I heard him (peace and blessings be upon him) saying: "O people! Do not complain about Ali, for by Allah, he is very stern and principled in matters concerning the Essence of Allah and His path." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
