islam does not Allow her to CUT herself out from her parents
SubhanAllah , only if u knew sis the beauty of Islam
Im sure u know all the verses about the parents and their rights in Islam
Just check this
Surah Luqman
14. And We have enjoined on man (to be dutiful and good) to his parents. His mother bore him in weakness and hardship upon weakness and hardship, and his weaning is in two years give thanks to Me and to your parents, unto Me is the final destination.
15. But if they (both) strive with you to make you join in worship with Me others that of which you have no knowledge, then obey them not, but behave with them in the world kindly, and follow the path of him who turns to Me in repentance and in obedience. Then to Me will be your return, and I shall tell you what you used to do
So in no way Islam teaches us to cut our selfes from our family n to harm them on any way , Rather it teaches us the oposite , BEHAVE with them kindly , treat them nicely n be good to them, Islam makes us a good person in al ways , a good son.daughter , Husban/wife , Islam insures parents rights like notthing else , So please dont make it look like she is in any way "destroying" a family Islam does not do that it actually does the opposite , Brings them together , makes te world a better place to live in each and every way.
And yes she cannot obey them in joining other in worship with Allah , but still she has t be good to them n obey them , The rights that Islam gives parents n the rank and position that Islam gives parents is just Amazing , read a book about parents rights In Islam.
Now if her reverting to Islam does in any way aftec her family or hurts them , I look at it like this , When some one is sick n needs to be cured n might need an operation would u not do his operation cz it will give them pain??? Or even an injection , if some one is sick will u just let them be sick n destroy thei rlife or give them an injections whose pain lasts only seconds.
Just imagine the pain n suffering of this world , taht wil end with the death , and compare it to eternal fire n tormet. It can never be compared. So if u really love some one u would want to FIX there hereafter , their next life and if by doing so they experience some sort of pain at all look at the big picture , u are saving them from something much biger , a pain n suffering much bigger.
Any way i just wanted to quote those verses that i quoted
