عَنْ هِشَامِ بْنِ عُرْوَةَ عَنْ أَبِيهِ قَالَ: سُئِلَ أُسَامَةُ بْنُ زَيْدٍ: كَيْفَ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَسِيرُ فِي حَجَّةِ الْوَدَاعِ حِينَ دَفَعَ؟ قَالَ: كَانَ يَسِيرُ الْعُنُق فَإِذا وجد فجوة نَص

Jabir said that the Prophet hastened from Jam' with a quiet demeanour and ordered the people to preserve a similar demeanour. He hastened in the wadi of Muhassir and ordered them to throw small pebbles, and he said, “Perhaps I shall not see you after this year.”I did not find this tradition in the two Sahihs, but in Tirmidhi's Jami’, with some transposition.
