It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) (like the previous saying). This is an authentic musnad hadith on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. Of this kind, they recorded the narration of Abu Ishaq containing the words: "There are only two things: guidance and speech. The best speech is the speech of Allah, and the best guidance is the guidance of Muhammad (peace and blessings be upon him)."

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to supplicate: 'Allahumma inni a'udhu bika min al-arba': min 'ilmin la yanfa', wa qalbin la yakhsha', wa nafsin la tashba', wa du'a'in la yusma'' (O Allah, I seek refuge in You from four things: from knowledge that does not benefit, from a heart that does not humble itself (before You), from a soul that is not satisfied, and from a supplication that is not accepted). This hadith is sahih (authentic), but they did not record it, because neither of them narrated from Abbad bin Abi Sa'id al-Maqburi, not because of any criticism of him, but because of the small number of his narrations and the little need for him.
