Surah 2. Al-Baqara, Ayah 222

This is one of the many references in the Qur'an to the positive, God-ordained nature of sexuality.

I.e., if they have transgressed against the above restriction.

 Do not have intercourse with them until their menstruation is over and they have taken a full bath.

Haithu: A comprehensive word referring to manner, time, or place. The most delicate matters are here referred to in the most discreet and yet helpful terms. In sex morality, manner, time, and place are all important: and the highest standards are set by social laws, by our own refined instinct of mutual consideration, and above all, by the light shed by the highest Teachers form the wisdom which they receive from our Maker, Who loves purity and cleanliness in all things.

Azan: hurt, pollution. Both aspects must be remembered. Physical cleanliness and purity make for health, bodily and spiritual. But the matter should be looked at from the woman's point of view as well as the man's. To her there is danger of hurt, and she should have every consideration. In the animal world, instinct is a guide which is obeyed. Man should in this respect be better: he is often worse.
