My mother-in-law together with my wife will be performing Umrah Insha Allah in May 2015. I will be acting as mahraam for both. As far as my mother-in-law is concerned, she don’t used to put hijab when going outside, put jeans/woman pants taking the shape of her body, cut and change the colour of her hair and used not to perform salaat on time when she can do so. Is it permissible?
