hitting children

Q: I am a 17 year old boy from Brisbane, Australia but orginaly from Pakistan and I was wondering if an Imam can advise me on a problem I am currently seeing happen with my own eyes. 

There is a 16 year old muslim girl whom I know very well, you can call me her best friend pretty much. She is from India and like me, she is also in her last year of school in Australia and university will start next year. Me and her have been friends since last year and were hoping that in 3 to 4 years Insha-Allah we will tell our parents about each other and arrange a marriage for us Insha-Allah. Unfortunately her parents are very abusive and strict parents, I have heard from her about the many different cases of them beating her up everyday for little things like forgetting to wash the laundry. Wallah I am not lying this is all true. A few weeks ago her mum was beating her up and said the following words to her "you are my daughter and I can do whatever I want to you and you can do nothing but obey me because I own you." I was absolutely shocked when I heard this. Wallahi all of this is true she has been constantly getting abused by her mum and dad since she was a little girl and her older brother seems to join in when he wants to. 

Recently, her parents told her that they want to get her engaged at the end of the year and she doesn't want this to happen. They have been forcing her to accept whatever they say and live with whoever they want and they made some cultural comments like no one else will be allowed to marry her except an Indian boy, no arab no pakistani no one except an Indian. She told me that she doesn't want this to happen and has been crying and feeling depressed from many days now. My question is, what is Islam's view on forced marriage and what can this girl do to avoid what her parents are doing because they have been abusing and forcing her to do as they say and she does not wish to get engaged to anyone by force and only wants to engage someone who she will accept with her heart but she feels like whoever her parents show her, she will only accept because of fear out of what they will do if she says no due to their abusive nature and not because she actually accepts the boy. 

If possible, can you please advise me on what this girl should do and how she can seek help? What does Islam say about a scenario like this and what can this girl do to avoid forced marriage? I am looking forward to the Imam's advice Insha-Allah it will be greatly appreciated.

Q: There are many madarasahs running in my locality. Specially those teaching kids. The ladies running the madarasa are too violent on kids. 3 year old kids, not even able to speak properly are asked to keep records of their prayers, and when these kids skip a prayer, mostly fajar, complaining that our mother didn't wake up us, the lady says that it's your responsibility to wake up not your mothers, and slap the kids so badly that their cheeks turn red and they begin crying. These ladies use dusting stick to hit on the kids palm so violently that the kids burst in tears. In case, when the kids could not memorise the lesson allocated to them yesterday, the ladies turn their ears in such a way that it's tongue comes out and the ear goes red and the kid cry aloud. Because of the crowd of kids, the lady running the madarasa has appointed other young girls to teach the very young and these girls are even more violent. In one of the madarasa the girl complaining that I couldn't wake up because my mother didn't wake me up was asked to pray 10 nafil to compensate the loss. They behave very badly with kids. Is it permissible to do this kind of violence in teaching Quran? Please support your views with AHaadith. What should I do being in the locality?

Q: I wanted to know that in which case hitting you own child or ustaad hitting a student becomes permissible? Lets say an ustaad has a student and if that student misbehaves or does an action which is total disrespect or doesn't follow ustaads instructions despite that ustaad keeps advising him apprehending and admonishing him (ustaad knows he has won the child's heart already and ustaad knows if he hits the student then the student will take that hiding in a positive way he is a student that wont have an aversion for deen after he gives it to him) he doesn't come right and then the ustaad feels the only solution in his case will be hitting him with justice so now will hitting him be allowed and permissible?
