(Second chain) Abdullah bin Haneen says: Sayyiduna Miswar bin Makhrama (may Allah be pleased with him) and Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) disagreed about whether a Muhrim can wash his head or not. Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) said: He can wash it, but Sayyiduna Miswar (may Allah be pleased with him) said: He cannot wash it. Both of them sent me to Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) so that I could ask him about this issue and return. When I went and asked him, he poured water on his head and moved his hands forward and backward, and then said: I had seen the Messenger of Allah (peace and blessings of Allah be upon him) do it in this way.
