Virtues of Harithah bin al-Nu'man (may Allah be pleased with him), son of Naf of Banu Ghanm bin Malik, with the kunyah Abu Abdullah; he took part in Badr and was martyred there

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both); he said: I heard the Messenger of Allah (peace and blessings be upon him) say: "The Throne of the Most Merciful shook at the death of Sa'd bin Mu'adh." A man said to Jabir: Al-Bara' (bin Azib) says that the (bier's) couch shook. Jabir replied: There were some old grudges between these two tribes, the Aws and the Khazraj (which is why the wording was changed); I myself heard the Messenger of Allah (peace and blessings be upon him) say: "The Throne of the Most Merciful shook at the death of Sa'd bin Mu'adh."
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) said: "I entered Paradise and heard the sound of recitation there. I asked: 'Who is this?' The angels replied: 'This is Harithah bin al-Nu'man.' (The reward of righteousness) is like this; the reward of kindness to parents is like this."
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
