It is narrated from Sayyiduna Abdullah bin Haneen (may Allah be pleased with him) that Sayyiduna Abdullah bin Abbas (may Allah be pleased with both of them) and Sayyiduna Miswar bin Makhramah (may Allah be pleased with him) had a disagreement at Abwa (which is a place between the two Harams). Sayyiduna Abdullah bin Abbas (may Allah be pleased with both of them) said: A Muhrim can wash his head. Sayyiduna Miswar bin Makhramah (may Allah be pleased with him) said: He cannot wash it. Sayyiduna Abdullah bin Haneen (may Allah be pleased with him) said: Sayyiduna Abdullah bin Abbas (may Allah be pleased with both of them) sent me to Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him), and I found him bathing between two wooden planks that were placed at the well, and he was screened with a cloth. I greeted him with salam. He asked: Who is this? I said: I am Abdullah bin Haneen. Sayyiduna Abdullah bin Abbas (may Allah be pleased with both of them) has sent me to ask you how the Messenger of Allah (peace and blessings be upon him) used to bathe when he was in the state of Ihram. So Sayyiduna Abu Ayyub (may Allah be pleased with him) placed his hand on the cloth and uncovered his head until his head became visible to me. Then he said to a man who was pouring water over him: Pour water. So he poured water on his head, and he (Abu Ayyub) moved both his hands over his head, bringing them forward and then backward, and said: This is how I saw the Messenger of Allah (peace and blessings be upon him) doing.
