It is narrated from Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him) that on the Day of Arafah a camel of mine went missing, so I set out towards Arafat to look for it, and I saw Muhammad (peace and blessings be upon him) standing on his camel among the people on the evening of Arafah, and this happened after revelation had come down to him (peace and blessings be upon him). This hadith has a sahih (authentic) chain of narration, but the two Shaykhs did not record it. Both of them agreed on the narration of Ibn Uyaynah which mentions the "Hums," and that the Messenger of Allah (peace and blessings be upon him) used to stand at a mountain pass of Makkah.
