The disapproval of wailing over the dead

It is narrated from Sayyiduna al-Nu'man bin Bashir (may Allah be pleased with him) that Sayyiduna Abdullah bin Rawahah (may Allah be pleased with him) fell unconscious, and his sister Amrah began to weep and to lament, listing his qualities: "Alas, my brother! Alas, you were such and such!" When he came to, he said: "For every quality you mentioned, I was questioned (by the angels): 'Are you really like that?'"
This hadith has an authentic (sahih) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Qays bin Abi Hazim that he said: I heard Sayyiduna Khalid bin al-Walid (may Allah be pleased with him) say: "On the day of the battle of Mu'tah, nine swords broke in my hand, and nothing remained in my hand except a single Yemeni blade."
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. Moreover, the two Shaykhs agreed on the hadith of Humayd bin Hilal from Sayyiduna Anas bin Malik (may Allah be pleased with him) concerning the battle of Mu'tah, that the Messenger of Allah (peace and blessings be upon him) said: "Zayd bin Harithah took the banner and was martyred, then Ja'far took it and was also martyred, then Abdullah bin Rawahah took it and was also martyred." After that the Messenger of Allah (peace and blessings be upon him) sent Khalid bin al-Walid (may Allah be pleased with him) to Mu'tah.

It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that she asked the wife of Sayyiduna Salamah bin Hisham bin al-Mughirah: "Why is it that I do not see Salamah attending the prayer with the Messenger of Allah (peace and blessings be upon him) and the Muslims?" She replied: "By Allah! He cannot go out (out of shame), because whenever he goes out, people call out to him: 'O you who fled! Did you run away from the path of Allah?' Because of this taunt he has become confined to his house and does not go out." It should be noted that he had taken part in the battle of Mu'tah with Khalid bin al-Walid (may Allah be pleased with him).
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 Hurayrah (may Allah be pleased with him) that he said: "A bitter exchange took place between me and a cousin of mine, and he said (taunting me): 'Are you not the one who fled on the day of Mu'tah?' When I heard this from him, I did not know what to answer him."
