Dear Friend
You have to understand Islam and then write such articles. With regret that you do not know about Islam and then wasting your time. I do not knw that much about the Fetwa but actually wh at you have written is completly out of principles. If you kill yourself, if you cut your organs, if you deprive your organs, if you do any sort of unfair acts with your body, ALLAH will ask you . So that is why suicide attacks are Haram and not eating is also Haram if you have food but not eat it j ust for your peronsal benefits. so I do not want to comment whether Barakzai was right or wrong but her strike was against of Islam and any such strikes are against of Islam. so my recommendation is t hat first read and get information about Islam and then write such articles.
