they ask you about womens menses. tell them it is an ailment. avoid having carnal relations with them until their period is over. then you may have carnal relations with them according to the rules of god. god loves those who repent and those who purify themselves.
ويسألونك عن المحيض قل هو أذى فاعتزلوا النساء في المحيض ولا تقربوهن حتى يطهرن فإذا تطهرن فأتوهن من حيث أمركم الله إن الله يحب التوابين ويحب المتطهرين
