Al-Baqarah 2:222 ويسالونك عن المحيض قل هو اذى فاعتزلوا النساء في المحيض ولا تقربوهن حتى يطهرن فاذا تطهرن فاتوهن من حيث امركم الله ان الله يحب التوابين ويحب المتطهرين ٢٢٢

They question thee (O Muhammad) concerning menstruation. Say: It is an illness, so let women alone at such times and go not in unto them till they are cleansed. And when they have purified themselves, then go in unto them as Allah hath enjoined upon you. Truly Allah loveth those who turn unto Him, and loveth those who have a care for cleanness.

And they ask you about menstruation. Say, "It is harm, so keep away from wives¹ during menstruation. And do not approach them until they are pure. And when they have purified themselves,² then come to them from where Allāh has ordained for you. Indeed, Allāh loves those who are constantly repentant and loves those who purify themselves."

They ask thee concerning women's courses. Say: They are a hurt and a pollution: So keep away from women in their courses, and do not approach them until they are clean. But when they have purified themselves, ye may approach them in any manner, time, or place ordained for you by Allah. For Allah loves those who turn to Him constantly and He loves those who keep themselves pure and clean.
