“The Messenger of Allah ﷺ departed during the Farewell Pilgrimage in a tranquil manner, and he urged them to be tranquil. He told them to throw small pebbles. He hastened through Muhassir Valley, and said: ‘Let my nation learn its rites (of Hajj), for I do not know, perhaps I will not meet them again after this year.’” (Using translation from Ibn Mājah 3023)
دَفَعَ رَسُولُ اللهِ ﷺ وَعَلَيْهِ السَّكِينَةُ وَأَوْضَعَ فِي وَادِي مُحَسِّرٍ وَأَرَاهُمْ مِثْلَ حَصَى الْخَذْفِ وَأَمَرَهُمْ بِالسَّكِينَةِ وَقَالَ لِتَأْخُذْ أُمَّتِي مَنَاسِكَهَا فَإِنِّي لَا أَدْرِي لَعَلِّي لَا أَلْقَاهُمْ بَعْدَ عَامِي هَذَا
