Sahih Muslim 1297
Sahih Muslim · Book 15: The Book of Pilgrimage · It is recommended to stone Jamrat Al-'Aqabah, on the day of sacrifice, riding, and the prophet saws said: "Learn your rituals (of Hajj) from me"
Jabir (Allah be pleased with him) reported:
حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ ، وَعَلِيُّ بْنُ خَشْرَمٍ، جَمِيعًا عَنْ عِيسَى بْنِ يُونُسَ ، - قَالَ ابْنُ خَشْرَمٍ أَخْبَرَنَا عِيسَى ، - عَنِ ابْنِ جُرَيْجٍ ، أَخْبَرَنِي أَبُو الزُّبَيْرِ ، أَنَّهُ سَمِعَ جَابِرًا ، يَقُولُ رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم يَرْمِي عَلَى رَاحِلَتِهِ يَوْمَ النَّحْرِ وَيَقُولُ " لِتَأْخُذُوا مَنَاسِكَكُمْ فَإِنِّي لاَ أَدْرِي لَعَلِّي لاَ أَحُجُّ بَعْدَ حَجَّتِي هَذِهِ " .
I saw Allah's Apostle (ﷺ) flinging pebbles while riding his camel on the Day of Nahr, and he was saying: Learn your rituals (by seeing me performing them), for I do not know whether I would be performing Hajj after this Hajj of mine.
