This is a non-sense subject. I don't know why this muslim guru's(ulemas) are believing that they are almighty and can force any one to obey their rules. Where were they when Pakistani actress Mira was banned by her own country . I think they just want to see thheir face in Television, Newspaper etc.There are number of instances where a muslim girl (in movies) doing nonsense things and they remain mum. Why don't they ask the underworld mafia's (many of them are muslims) that not to commit the murder, kidnapping etc. etc,. I believe this things are prohibited in Muslim law. They only come forward when they see that the opponent is weak like Imrana, or there is chance of media publishment.
Only for their threat on sania , I believe Sania has a bad tourney after US Open, where she was defeated in the 1st Round. These threats may be in her mind and may be she cant concentrate on her game.
