It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Show mercy to those on the earth, and the One who is above the heaven will show mercy to you." 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 Abu Hurayrah (may Allah be pleased with him) that my intimate friend and chosen beloved, the owner of this chamber (peace and blessings be upon him), said: "Mercy is taken away only from the heart of a wretched person." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it. This Abu Uthman is the freed slave of al-Mughirah, not al-Nahdi; had he been al-Nahdi, I would have judged it sahih on the condition of the two Shaykhs.
