Sunan an-Nasa'i, Volume 3, Book 24, Hadith 3028 (DarusSalam) ⓘ

It was narrated that Usmah bin Zaid said: "The Messenger of allah stopped in the mountain pass where the rulers stop now, and urinated, then he performed a light Wudu and I said: 'O Messenger of Allah (isit time for ) prayer?' He said: 'The prayer is still ahead of you.' When we came to Al-Muzdalifah the people did not unload their camles until he had prayed."

أَخْبَرَنَا مَحْمُودُ بْنُ غَيْلاَنَ، قَالَ حَدَّثَنَا وَكِيعٌ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ إِبْرَاهِيمَ بْنِ عُقْبَةَ، عَنْ كُرَيْبٍ، عَنْ أُسَامَةَ بْنِ زَيْدٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَزَلَ الشِّعْبَ الَّذِي يَنْزِلُهُ الأُمَرَاءُ فَبَالَ ثُمَّ تَوَضَّأَ وُضُوءًا خَفِيفًا فَقُلْتُ يَا رَسُولَ اللَّهِ الصَّلاَةَ ‏.‏ قَالَ ‏ "‏ الصَّلاَةُ أَمَامَكَ ‏" ‏ ‏.‏ فَلَمَّا أَتَيْنَا الْمُزْدَلِفَةَ لَمْ يَحُلَّ آخِرُ النَّاسِ حَتَّى صَلَّى ‏.‏
