Kathir bin Jumhan says that I saw Sayyiduna Ibn Umar (may Allah be pleased with them both) walking at a normal pace between Safa and Marwah, so I asked him, "Are you walking at a normal pace?" He replied: "If I walk at a normal pace, then I have seen the Prophet (peace and blessings be upon him) walking like this as well, and if I walk briskly, then I have also seen the Prophet (peace and blessings be upon him) walking like that."
