Nafi’ (may Allah have mercy on him) says that Sayyiduna Ibn Umar (may Allah be pleased with them both) used to perform ramal from the Black Stone to the Black Stone, and he used to inform us that the Prophet (peace and blessings be upon him) also did the same, and he would walk at a normal pace between the Yemeni Corner and the Black Stone so that it would be easier to perform istilam.
