Kuthair bin Jumhan narrates that I saw Sayyiduna Ibn Umar (may Allah be pleased with them both) walking at a normal pace between Safa and Marwah, so I said to him (that you are walking at a normal pace at the place where people usually run). He replied, "If I walk at a normal pace, then I have seen the Messenger of Allah (peace be upon him) walking at a normal pace. And if I run, then I have also seen the Messenger of Allah running."
