Sunan Abi Dawud 1945
Narrated Abdullah ibn Umar:
The Messenger of Allah (ﷺ) halted on the day of sacrifice between the jamrahs (pillars at Mina) during hajj which he performed. He asked: Which is this day? They replied: This is the day of sacrifice. He said: This is the day of greater hajj.
حَدَّثَنَا مُؤَمَّلُ بْنُ الْفَضْلِ، حَدَّثَنَا الْوَلِيدُ، حَدَّثَنَا هِشَامٌ، - يَعْنِي ابْنَ الْغَازِ - حَدَّثَنَا نَافِعٌ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم وَقَفَ يَوْمَ النَّحْرِ بَيْنَ الْجَمَرَاتِ فِي الْحَجَّةِ الَّتِي حَجَّ فَقَالَ ‏"‏ أَىُّ يَوْمٍ هَذَا ‏"‏ ‏.‏ قَالُوا يَوْمُ النَّحْرِ ‏.‏ قَالَ ‏"‏ هَذَا يَوْمُ الْحَجِّ الأَكْبَرِ ‏"‏ ‏.‏
