Muwatta Malik, Book 20, Hadith 109 (USC-MSA)

Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to hasten from the Black Stone round to the Black Stone three times and then would walk four circuits normally.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ يَرْمُلُ مِنَ الْحَجَرِ الأَسْوَدِ إِلَى الْحَجَرِ الأَسْوَدِ ثَلاَثَةَ أَطْوَافٍ وَيَمْشِي أَرْبَعَةَ أَطْوَافٍ ‏.‏
