Sahih Muslim Book 003, Hadith Number 0592.

Chapter : The menstruating woman is permitted to wash the head of her husband, comb his hair, and her left-over is clean, and one is permitted to recline in her lap and recite the Qur'an.

Thabit narrated it from Anas: Among the Jews, when a woman menstruated, they did not dine with her, nor did they live with them in their houses; so the Companions of the Apostle (may peace be upon him) asked The Apostle (may peace be upon him), and Allah, the Exalted revealed: "And they ask you about menstruation; say it is a pollution, so keep away from woman during menstruation" to the end (Qur'an, ii. 222). The Messenger of Allah (may peace be upon him) said: Do everything except intercourse. The Jews heard of that and said: This man does not want to leave anything we do without opposing us in it. Usaid b. Hudair and Abbad b. Bishr came and said: Messenger of Allah, the Jews say such and such thing. We should not have, therefore, any contact with them (as the Jews do). The face of the Messenger of Allah (way peace be upon him) underwent such a change that we thought he was angry with them, but when they went out, they happened to receive a gift of milk which was sent to the Apostle of Allah (may peace be upon him). He (the Holy Prophet) called for them and gave them drink, whereby they knew that he was not angry with them.
