It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that Sayyiduna Muawiyah bin Sufyan (may Allah be pleased with him) informed him. He said: I cut the hair of the Messenger of Allah (peace and blessings of Allah be upon him) on (the hill of) Marwah with the blade of an arrow. (Or he said: I saw the Messenger of Allah (peace and blessings of Allah be upon him) on Marwah having his hair cut with the blade of an arrow.)
