All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
First of all, you should know that the father of a girl –who is her guardian –is not permitted to absolutely prevent his daughter from marriage. If he prevents her, he loses his guardianship over her, and her guardianship moves to a Muslim judge. Therefore, if you know that your father does not want to marry you off at all, then you may appoint one of the Islamic Centres to marry you off and you are not sinful for doing so.

We advise you to fear Allaah and remain steadfast on His Obedience and perform good deeds. Besides, you should be keen on pleasing your parents as much as possible, and return to live with them if this is possible. Additionally, you should endeavour to advise your brother and exert your efforts in order to convince him to allow you to live with them. Then if he refuses, you should endeavour to please your parents even though your brother is discontent. If you make an effort to please them and they still did not allow you to live with them, then you are not sinful for not living with them. In such case, you should be kind and dutiful to them and fulfil their needs according to your ability and visit them from time to time and offer them gifts.
You should beware of the whispers of the devil who wants you to abandon the prayer on the pretext that your parents are not pleased with her. Will your Lord and your father be happy with you if you abandon your prayer? Your situation will be even worse and you will become even farther from Allaah; this is exactly what the devil wants from you. Your statement that your prayer will not be accepted if your parents are not pleased with you is not correct; this is neither proved in the Quran nor the Sunnah of the Prophet .
If you exert your efforts to please your parents and repent to Allaah from causing their anger against you, then Allaah will accept your repentance, Allaah willing, even if your parents are not pleased with you. That is because you would have done what you are religiously required to do. What is within your reach to do is to repent and try to please your parents, and Allaah does not burden a soul more than it can bear.
We think that if you live with your parents and they find out about your steadfastness on religion and you try to mend the past, then there is no doubt that they will be pleased with you because their instinctive affection which parents usually have towards their children will be revived.
Therefore, you should take the initiative to do this and remember the Saying of Allaah (which means): {And whoever fears Allaah -- He will make for him of his matter ease.}[Quran 65:4] Allaah also Says (what means): {Say, “O My servants who have transgressed against themselves [by sinning] do not despair of the Mercy of Allaah. Indeed, Allaah forgives all sins. Indeed, it is He Who is the Forgiving, the Merciful.}[Quran 39:53]
For more benefit, please refer to Fataawa 86982, 87019 and 84800.
Finally, we would like to stress the seriousness of abandoning the prayer and being lured by the whispers of the devil (for abandoning it).
We ask Allaah to enable you to do what He loves and what pleases Him.
