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.  

أَنَّهُ سَمِعَ جَابِرًا يَقُولُ رَأَيْتُ النَّبِيَّ ﷺ يَرْمِي عَلَى رَاحِلَتِهِ يَوْمَ النَّحْرِ وَيَقُولُ لِتَأْخُذُوا مَنَاسِكَكُمْ فَإِنِّي لاَ أَدْرِي لَعَلِّي لاَ أَحُجُّ بَعْدَ حَجَّتِي هَذِهِ  

I saw the Messenger of Allah ﷺ throwing pebbles on the day of sacrifice while on his riding beast and saying: Learn your rites, for I do not know whether I am likely to perform Hajj after this occasion.  

سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ يَقُولُ رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَرْمِي عَلَى رَاحِلَتِهِ يَوْمَ النَّحْرِ يَقُولُ 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. (Using translation from Muslim 1297)  

أَنَّهُ سَمِعَ جَابِرًا يَقُولُ رَأَيْتُ النَّبِيَّ ﷺ يَرْمِي عَلَى رَاحِلَتِهِ يَوْمَ النَّحْرِ يَقُولُ لِتَأْخُذُوا مَنَاسِكَكُمْ فَإِنِّي لَا أَدْرِي لَعَلِّي لَا أَحُجَّ بَعْدَ حَجَّتِي هَذِهِ  

[Machine] He said: The Messenger of Allah ﷺ threw pebbles at the Jamrah while on his camel and said, "Take from your rituals, for I do not know if I will ever perform Hajj again after this year."  

أَنَّهُ قَالَ رَمَى رَسُولُ اللهِ ﷺ الْجَمْرَةَ عَلَى بَعِيرِهِ بِحَصَى الْخَذْفِ وَهُوَ يَقُولُ لِتَأْخُذُوا مَنَاسِكَكُمْ فَإِنِّي لَا أَدْرِي لَعَلِّي لَا أَحُجُّ بَعْدَ حَجَّتِي هَذِهِ  

"يَا أَيُّهَا النَّاسُ: خُذوا عَنِّى مناسِكَكُمْ؛ فَإِنِّى لا أَدْرى لَعَلِّى لا أَحُجُّ بَعْد عامى هذا".
