Kuthair bin Jumhan Salmi narrates that I saw Sayyiduna Ibn Umar (may Allah be pleased with them both) walking at a normal pace in the area for running (the low area between Safa and Marwah), so I said to him, "Why are you walking at a normal pace in the running place between Safa and Marwah?" He replied, "If I run, then I have seen the Prophet Muhammad (peace and blessings be upon him) running. And if I walk at a normal pace, then indeed I have seen the Messenger of Allah (peace and blessings be upon him) walking at a normal pace as well, and I am an old man (that is why I am walking at a normal pace)."
