Usayd bin Hudayr (may Allah be pleased with him) playfully kissing the side of the Prophet (peace and blessings be upon him)

Abd al-Rahman bin Abi Layla narrates from his father that Sayyiduna Usayd bin Hudayr (may Allah be pleased with him) was a cheerful and good-humoured man. Once, while he was talking with the people who were with the Messenger of Allah (peace and blessings be upon him) and making them laugh, the Messenger of Allah (peace and blessings be upon him) poked him (in jest) in his side. Usayd said: "You have hurt me." He (peace and blessings be upon him) said: "Take your retaliation then." He said: "O Messenger of Allah! You are wearing a shirt, whereas I had no shirt on my body (when you poked me)." The narrator said: So the Messenger of Allah (peace and blessings be upon him) lifted his blessed shirt, whereupon Usayd (may Allah be pleased with him) embraced him (peace and blessings be upon him) and began kissing his (peace and blessings be upon him) sides, and then said: "O Messenger of Allah! May my father and mother be ransomed for you, this is all I wanted." These are the words of the narration of Jarir from Husayn, whereas the hadith of Warqa' is abridged.
This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "What an excellent man Usayd bin Hudayr is!"
This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
