Abdullah bin Abbas and Miswar bin Makhrama disagreed with one another at Abwa.Abdullah said, "A pilgrim consecrated for pilgrimage may wash his head."Miswar bin Makhrama said, "A pilgrim consecrated for pilgrimage may not wash his head."Abdullah bin Hunayn reported, So Abdullah bin Abbas sent me to Abu Ayub Ansari, and I found him bathing between the two posts of a well, screened by a cloth. I greeted him.He asked, "Who is this?"I said, "I am Abdullah bin Hunayn. Abdullah bin Abbas has sent me to you to ask how the Messenger of Allah ﷺ used to wash his head while he was consecrated for pilgrimage."Abu Ayub put his hand on the cloth and lowered it until his head came into view. Then he said to a man who was pouring water for him, "Pour." So the man poured water over his head, and Abu Ayub moved his hair with his hands, bringing them forward and back. Then he said, "This is how I saw the Messenger of Allah ﷺ do it."
حدثني يحيى عن مالك عن زيد بن أسلم
أن عبد الله بن عباس والمسور بن مخرمة اختلفا بالأبواء فقال عبد الله يغسل المحرم رأسه وقال المسور بن مخرمة لا يغسل المحرم رأسه قال فأرسلني عبد الله بن عباس إلى أبي أيوب الأنصاري فوجدته يغتسل بين القرنين وهو يستر بثوب فسلمت عليه فقال من هذا فقلت أنا عبد الله بن حنين أرسلني إليك عبد الله بن عباس أسألك كيف كان رسول الله ﷺ يغسل رأسه وهو محرم قال فوضع أبو أيوب يده على الثوب فطأطأه حتى بدا لي رأسه ثم قال لإنسان يصب عليه اصبب فصب على رأسه ثم حرك رأسه بيديه فأقبل بهما وأدبر ثم قال هكذا رأيت رسول الله ﷺ يفعل
