Entitled by law

TFTD: Entitled by law Are residents in the Islamic State ENTITLED by law to have provisions made to accommodate their religious convictions, even if these were to differ from the khalifah's adoption?

For example, would Shabina Begum have had the right to demand her school accommodate her jilbab, if the khalifah had adopted that the jilbab was not obligatory?

Would this apply to other faiths too?
