Sahih al-Bukhari, Hadith 1644 ⓘ

Narrated Nafi`: Ibn `Umar said, "When Allah's Messenger performed the first Tawaf he did Ramal in the first three rounds and then walked in the remaining four rounds (of Tawaf of the Ka`ba), where as in performing Tawaf between Safa and Marwa he used to run in the midst of the rainwater passage," I asked Nafi`, "Did `Abdullah (bin `Umar) use to walk steadily on reaching the Yemenite Corner?" He replied, "No, unless people were crowded at the Corner; otherwise he would not leave it without touching it."

حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدِ بْنِ مَيْمُونٍ، حَدَّثَنَا عِيسَى بْنُ يُونُسَ، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا طَافَ الطَّوَافَ الأَوَّلَ خَبَّ ثَلاَثًا وَمَشَى أَرْبَعًا، وَكَانَ يَسْعَى بَطْنَ الْمَسِيلِ إِذَا طَافَ بَيْنَ الصَّفَا وَالْمَرْوَةِ‏.‏ فَقُلْتُ لِنَافِعٍ أَكَانَ عَبْدُ اللَّهِ يَمْشِي إِذَا بَلَغَ الرُّكْنَ الْيَمَانِيَ قَالَ لاَ‏.‏ إِلاَّ أَنْ يُزَاحَمَ عَلَى الرُّكْنِ فَإِنَّهُ كَانَ لاَ يَدَعُهُ حَتَّى يَسْتَلِمَهُ‏.‏
