Sahih al-Bukhari 1669
صحيح البخاري#1669SahihNarrated Usama bin Zaid:I rode behind Allah's Messenger (ﷺ) from `Arafat and when Allah's Messenger (ﷺ) reached the mountain pass on the left side which is before Al-Muzdalifa he made his camel kneel and then urinated, and then I poured water for his ablution. He performed light ablution and then I said to him: (Is it the time for) the prayer, O Allah's Messenger (ﷺ)!" He replied, "The (place of) prayer is ahead of you (i.e. at Al- Muzdalifa)." So Allah's Messenger (ﷺ) rode till he reached Al-Muzdalifa and then he offered the prayer (there) . Then in the morning (10th Dhul-Hijja) Al-Faql (bin `Abbas) rode behind Allah's Messenger (ﷺ). Kuraib, (a sub-narrator) said that `Abdullah bin `Abbas narrated from Al-Fadl, "Allah's Messenger (ﷺ) kept on reciting Talbiya (during the journey) till he reached the Jamra." (Jamrat-Al-`Aqaba)
