Narrated by Sayyiduna Abdullah bin Umar (may Allah be pleased with them both): When the Prophet (peace and blessings of Allah be upon him) performed the first circumambulation (i.e., Tawaf al-Qudum) of the Ka'bah, he would walk briskly in three of its circuits and walk normally in four. Then, when he performed Sa'i between Safa and Marwah, he would run in the valley (Batn al-Masil).
