Compiled by Imam Muhammad al-Bukhari
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ هِشَامٍ، قَالَ حَدَّثَنِي أَبِي قَالَ، سُئِلَ أُسَامَةُ وَأَنَا شَاهِدٌ، عَنْ سَيْرِ النَّبِيِّ، صلى الله عليه وسلم فِي حَجَّتِهِ. فَقَالَ الْعَنَقَ، فَإِذَا وَجَدَ فَجْوَةً نَصَّ.
In my presence, Usama was asked about the speed of the Prophet (ﷺ) during his Hajj. He replied, "It was Al-`Anaq (i.e. moderate easy speed) and if he encountered an open space, he used to increase his speed."
