Why we keep our woman in hijab?

Why we keep our woman in hijab?
Because we love our woman 
Because we respect our woman 
Because we don't sale our woman in the name of modelling and sex market 
Because we treat our woman like queen because we keep them like diamonds 
Because we obey Allah the creator of universe but we don't worship the creation 
Because we are slave of Crestor Allah but we are not slaves of creation
