Muwatta Imam Malik Book of Hajj, Hadith 185

Yahya related to me from Malik from Hisham ibn Urwa that his father said, "I was sitting with Usama ibn Zayd when some one asked him, 'How did the Messenger of Allah ﷺ travel when he went from Arafa to Muzdalifa during the farewell hajj?' and he replied, 'He went at a medium pace, but when he found a gap (in the crowds) he speeded up.' "

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، أَنَّهُ قَالَ سُئِلَ أُسَامَةُ بْنُ زَيْدٍ - وَأَنَا جَالِسٌ، مَعَهُ - كَيْفَ كَانَ يَسِيرُ رَسُولُ اللَّهِ ﷺ فِي حَجَّةِ الْوَدَاعِ حِينَ دَفَعَ قَالَ كَانَ يَسِيرُ الْعَنَقَ فَإِذَا وَجَدَ فَجْوَةً نَصَّ . قَالَ مَالِكٌ قَالَ هِشَامٌ وَالنَّصُّ فَوْقَ الْعَنَقِ .
