is hacking for a good cause allowed in islam?

[scarlett]

first i’d like to give you an introduction so you don’t get the wrong idea.i know i shouldn’t be here but i am, for my muslim friend who is a really good in studies and one of her favourite subjects is computer sciences and when she was studying programming she got really deep and then particularly in hacking because she thought she might use it to keep a check her brother without knowing this was neither legal nor allowed in islam.(she’s not some professional, only a 14 year old).
she came to know when: a couple of days ago some guys and girls in our class, who knew that she knew hacking, begged her to remove their names from the troll and crushes page of our school and for the first time she hacked an outsider’s page on facebook. she first removed their names and then warned that guy not to do this stuff and thats when he told her he’ll instead report her as a hacker and tell our school or authorities and her parents etc if she doesn’t mind her own bussiness and she came to know…
she had been hacking her brother’s accounts(who’s a year older) on all socail media networks or sometimes his entire mobile internet. she didn’t do it for herself but for her single hardworking mother. she does not want her mother to know about the stuff that he does, since the mommy’s satisfied by him getting the best grades in class and so she doesn’t want to see her get hurt, hence she takes these precautions.
her brother is always humiliating her and she has always been solving his problems. there almost hasn’t been a week when she wasn’t called by his teachers or principle and then as she enters the class everyone’s like so what did your brother do this time? she’s been hiding and dealing his fights, detensions, hook ups with girls and so much more. blackmailing him by telling him she’ll tell all this stuff to her mom was the only solution to get him away of this stuff. he had even got to a point when he started watching porn. having controle over his whole socail media networking or internet is the only way for her to somewhat keep her brother away from this stuff.

i’d appriciate your immidiate response. thanks.

and she was confused because according to her knowledge of islam you’re not allowed to disturb someone’s privacy as the quran says

“O you who Believe avoid much suspicion, indeed some suspicion is a sin. And spy not on one an other neither backbite one another.” [EMQ 49:12] authority of Abu Hurairah that the Messenger Muhammad (saw) said: “Beware of suspicion, for suspicion is the worst of false tales. Do not look for others faults, do not spy on one another, do not practice najash (biding over one another), do not be jealous of one another, do not hate one another and do not desert or stop talking to one another. O Allah’s worshippers, be brothers”.

but on the other side: Abu Saeed al-Khudri (may Allah be pleased with him) who said: I heard the Messenger of Allah say, “Whoever of you sees an evil must then change it with his hand. If he is not able to do so, then [he must change it ] with his tongue. And if he is not able to do so, then [he must change it] with his heart. And that is the slightest [effect of] faith.” and mentioned in muslim: “Whoever conceals [the faults of] a Muslim, Allah will conceal [his faults] in this life and the Hereafter.”
she puts islam before everything, is a really nice person and everyone turns to her for help regardless of her age. they use her when needed and ignore her when they’re done taking advantage of her innocence and her religion(things that make her help others) and so i really want to help her through this time. she’s really scared and confused and keeps on asking for forgiveness from her god. and i’m not asking about how to get rid of that facebook guy , just what islam says about hacking for a good cause like keeping ur brother from bad stuff.

Welcome to the forum. No, hacking is not allowed in Islam. If you want to do something then do it properly. This should be the adults' responsibility to take care of what their kids are doing and be more aware and vigilant about whats happening in their lives.
