Hazrat Haneen says that Hazrat Ibn Abbas (may Allah be pleased with them both) and Hazrat Miswar bin Makhrama had a disagreement regarding washing the head while in the state of Ihram. He sent me to Hazrat Abu Ayyub. When I came to him, he was bathing at a well. I said to him, "Hazrat Ibn Abbas (may Allah be pleased with them both), your nephew, has sent me to you and asked how you saw the Messenger of Allah (peace and blessings be upon him) wash his head while in the state of Ihram?" He took water and poured it over his head, then he moved forward and backward, and said, "I saw the Messenger of Allah (peace and blessings be upon him) wash his head in the state of Ihram in this manner." Then I returned to those companions and informed them of what he had said. Hazrat Miswar said, "I will never disagree with you after this."

Hazrat Muslim al-Qari says that I asked Hazrat Ibn Abbas (may Allah be pleased with them), "Can I pour water on my head while in the state of Ihram?" He replied, "There is no harm in that. Indeed, Allah the Exalted says { اِنَّ اللّٰہَ یُحِبُّ التَّوَّابِیْنَ وَ یُحِبُّ الْمُتَطَھِّرِیْنَ } Allah the Exalted loves those who repent and those who keep themselves clean."
