Narrated `Urwa (R.a):
A person asked me, “Can a woman in menses serve me?
And can a Junub woman come close to me?”
I replied, “All this is easy for me. All of them can serve me, and there is no harm for any other person to do the same.
`Aisha told me that she used to comb the hair of Allah’s Messenger Salallahu alaihi wassalam while she was in her menses, and he was in I`tikaf (in the mosque).
He would bring his head near her in her room and she would comb his hair, while she used to be in her menses.”
