The Rites of Hajj (Kitab Al-Manasik Wa'l-Hajj)
حَدَّثَنَا ابْنُ الْعَلاَءِ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ إِسْمَاعِيلَ، عَنْ أَبِي إِسْحَاقَ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، قَالَ أَفَضْنَا مَعَ ابْنِ عُمَرَ فَلَمَّا بَلَغْنَا جَمْعًا صَلَّى بِنَا الْمَغْرِبَ وَالْعِشَاءَ بِإِقَامَةٍ وَاحِدَةٍ ثَلاَثًا وَاثْنَتَيْنِ فَلَمَّا انْصَرَفَ قَالَ لَنَا ابْنُ عُمَرَ هَكَذَا صَلَّى بِنَا رَسُولُ اللَّهِ صلى الله عليه وسلم فِي هَذَا الْمَكَانِ .
Sa’id bin Jubair said “We returned along with Ibn ‘Umar and when we reached Al Muzdalifah he led us in the sunset and night prayers with one iqamah and three rak’ahs of the sunset prayer and two rak’ahs of the night prayer. When he finished the prayer Ibn ‘Umar said to us The Messenger of Allah (ﷺ) led us in prayer in this way at this place.”
