Hadith 8:211
Abu Bakr narrated to us, he said: Ibn ‘Uyaynah narrated to us, from Zayd ibn Aslam, from Ibrahim ibn ‘Abd Allah ibn Hunayn, from his father, who said: Ibn ‘Abbas and al-Miswar ibn Makhramah differed regarding the *muhrim* (a person in the state of ihram) washing his head. He said: My affair is to Abu Ayyub. So I came to him while he was between the two pillars of the well, bathing. I said: "Indeed, your nephew, Ibn ‘Abbas, has sent me to you, saying: 'How did you see the Messenger of Allah, may Allah bless him and grant him peace, wash his head while he was a *muhrim*?'" He took some water and poured it over his head, then he moved forward and backward. He said: "Thus I saw the Messenger of Allah, may Allah bless him and grant him peace, do while he was a *muhrim*." I returned to them both and informed them of his statement. Al-Miswar said: "I will never disagree with you."
حدثنا أبو بكر قال ثنا بن عيينة عن زيد بن أسلم عن إبراهيم بن عبد الله بن حنين عن أبيه قال اختلف بن عباس والمسور بن مخرمة في المحرم يغسل رأسه قال شأني إلى أبي أيوب فأتيته وهو بين قرني ( البئر ) يغتسل فقلت إن بن اختك بن عباس أرسلني إليك يقول كيف رأيت رسول الله صلى الله عليه وسلم يغسل رأسه وهو محرم فأخذ من الماء فصبه على رأسه ثم أقبل وأدبر قال هكذا رأيت رسول الله صلى الله عليه وسلم يفعل وهو محرم فرجعت إليهما فأخبرتهما بقوله فقال المسور لا أخالفك أبدا
