they ask you about menstruation. say it is an impurity so keep away from women during it and do not approach them until they are cleansed when they are cleansed you may approach them as god has ordained. god loves those who turn to him in penitence and he loves those who keep themselves clean.
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
