Sunan Ibn Majah Book 25, Hadith 3019

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، حَدَّثَنَا سُفْيَانُ، عَنْ إِبْرَاهِيمَ بْنِ عُقْبَةَ، عَنْ كُرَيْبٍ، عَنْ أُسَامَةَ بْنِ زَيْدٍ، قَالَ أَفَضْتُ مَعَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فَلَمَّا بَلَغَ الشِّعْبَ الَّذِي يَنْزِلُ عِنْدَهُ الأُمَرَاءُ نَزَلَ فَبَالَ وَتَوَضَّأَ قُلْتُ الصَّلاَةَ ‏.‏ قَالَ ‏ "‏ الصَّلاَةُ أَمَامَكَ ‏"‏ ‏.‏ فَلَمَّا انْتَهَى إِلَى جَمْعٍ أَذَّنَ وَأَقَامَ ثُمَّ صَلَّى الْمَغْرِبَ ثُمَّ لَمْ يَحِلَّ أَحَدٌ مِنَ النَّاسِ حَتَّى قَامَ فَصَلَّى الْعِشَاءَ ‏.‏

It was narrated that Usamah bin Zaid said:“I departed from ‘Arafat with the Messenger of Allah (ﷺ), and when he reached the mountain path at which the chiefs would dismount, he dismounted and urinated, then performed ablution. I said: ‘(Is it time for) prayer?’ He said: ‘The prayer is still ahead of you.’ When he reached Jam’ (Muzdalifah) he called the Adhan and Iqamah, then he prayed Maghrib. Then no one among the people unloaded (the camels) until he had prayed ‘Isha’.”
