Hadith 2940
أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ يَرْمُلُ الثَّلاَثَ وَيَمْشِي الأَرْبَعَ وَيَزْعُمُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَفْعَلُ ذَلِكَ .
It was narrated from Nafi that:
Abdulla bin Umar used to walk rapidly for three (rounds), and walk for four, and he said that the Messenger of Allah used to do that.
