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

Yahya related to me from Malik from Hisham ibn Urwa that hisfather said, "I was sitting with Usama ibn Zayd when some one askedhim, 'How did the Messenger of Allah, may Allah bless him and granthim peace, travel when he went from Arafa to Muzdalifa during thefarewell hajj?' and he replied, 'He went at a medium pace, but when hefound a gap (in the crowds) he speeded up.'
