حَدَّثَنَا يَحْيَى عَنْ عُبَيْدِ اللَّهِ أَخْبَرَنِي نَافِعٌ عَنِ ابْنِ عُمَرَ أَنَّهُ كَانَ يَرْمُلُ ثَلَاثًا وَيَمْشِي أَرْبَعًا وَيَزْعُمُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَفْعَلُهُ وَكَانَ يَمْشِي مَا بَيْنَ الرُّكْنَيْنِ قَالَ إِنَّمَا كَانَ يَمْشِي مَا بَيْنَهُمَا لِيَكُونَ أَيْسَرَ لِاسْتِلَامِهِ
مسند امام احمد بن حنبل · Hadith 4618
It was narrated from Ibn 'Umar that he used to walk rapidly in (the first) three (circuits of tawaaf) and walk in (the last) four, and he said that the Messenger of Allah (PBUH) used to do that, a n d he used to walk between the two corners (the Yemeni corner and the corner where the Black Stone is), and he said: He only used to walk between them so that it would be easier to touch them.
