In my presence, Usama was asked about the speed of the Prophet ﷺ during his Hajj. He replied, "It was Al-ʿAnaq (i.e. moderate easy speed) and if he encountered an open space, he used to increase his speed."
عَنْ سَيْرِ النَّبِيِّ ﷺ فِي حَجَّتِهِ فَقَالَ الْعَنَقَ فَإِذَا وَجَدَ فَجْوَةً نَصَّ
Usama bin Zaid was asked at what pace the Prophet ﷺ rode during Hajjat-ul-Wadaʿ "He rode at a medium pace, but when he came upon an open way he would go at full pace."
عَنْ مَسِيرِ النَّبِيِّ ﷺ فِي حَجَّةِ الْوَدَاعِ قَالَ فَكَانَ يَسِيرُ الْعَنَقَ فَإِذَا وَجَدَ فَجْوَةً نَصَّ وَالنَّصُّ فَوْقَ الْعَنَقِ
"He used to ride at a moderately fast pace, and when he came upon some open space he would gallop."
عَنْ مَسِيرِ النَّبِيِّ ﷺ فِي حَجَّةِ الْوَدَاعِ قَالَ كَانَ يَسِيرُ الْعَنَقَ فَإِذَا وَجَدَ فَجْوَةً نَصَّ وَالنَّصُّ فَوْقَ الْعَنَقِ
"He used to ride at a moderately fast pace, and when he came upon some open space he would gallop." (Using translation from Nasāʾī 3023)
عَنْ مَسِيرِ النَّبِيِّ ﷺ فِي حَجَّةِ الْوَدَاعِ فَقَالَ «كَانَ يَسِيرُ الْعَنَقَ فَإِذَا وَجَدَ فَجْوَةً نَصَّ وَالنَّصُّ فَوْقَ الْعَنَقِ»
