I am sure you know the meaning of Allah O Akbar. If Allah is great & Koran is the truth then how can you say that true believer of Islam should kill Sania Mirza. That means you are neither a Muslim nor you have ever read Koran. By saying that her breast is clearly visible then hiprocrate like you just look at her vital stats only..so are you not unislamic person so fatwa has to be issued in your name also for looking at female in a bad sense which is prohibited in Islam. So before killing Sania Mirza you should be the first person to be killed. So refrain from such things and think about Allah, Prophet Mohammad Sala O Sallam..do good deeds...
