One such is the recent story of the marriage registrar, or more accurately the woman who wished to be a marriage registrar.
She was refused the job because at times — during menstruation say — she would not be able to enter the mosque and therefore would not be able to work.
My own answer to this would be to appoint her along with the instruction that she should give warning, in advance, of her period.
Those who would use that mosque, or those mosques, for their marriages, would then have to wait and much good it will do them to face their prejudices.
But then I am not noted for the delicacy with which I approach religious questions.
