Sunan Ibn Majah, Volume 4, Book 25, Hadith 3023 (DarusSalam) ⓘ
Jabir said: “The Messenger of Allah 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.’”
حَدَّثَنَا مُحَمَّدُ بْنُ الصَّبَّاحِ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ رَجَاءٍ الْمَكِّيُّ، عَنِ الثَّوْرِيِّ، قَالَ قَالَ أَبُو الزُّبَيْرِ قَالَ جَابِرٌ أَفَاضَ النَّبِيُّ ـ صلى الله عليه وسلم ـ فِي حَجَّةِ الْوَدَاعِ وَعَلَيْهِ السَّكِينَةُ وَأَمَرَهُمْ بِالسَّكِينَةِ وَأَمَرَهُمْ أَنْ يَرْمُوا بِمِثْلِ حَصَى الْخَذْفِ وَأَوْضَعَ فِي وَادِي مُحَسِّرٍ . وَقَالَ " لِتَأْخُذْ أُمَّتِي نُسُكَهَا فَإِنِّي لاَ أَدْرِي لَعَلِّي لاَ أَلْقَاهُمْ بَعْدَ عَامِي هَذَا " .
